what is a radius


Let us learn what is a radius?


The space from the center to the edge of a circle

it is 1/2 of the circle's diameter is called radius
Find the diameter of the circle whose area is 22cm.
Solution:
Given that the area of the circle is 22cm.
Area of the circle = pi *r2
22 = pi * r2
22 = 3.14 * r2
Divide by 3.14 on both sides
22/3.14 = 3.14 * r2/3.14
71.66 = r2
r = √7.01
r = 2.65cm.
Diameter of a circle = 2 * radius
= 2 * 2.65
=5.3cm.

electric range parts



Let us learn about electric range parts.

Electric ranges are useful the main reason why people use Electric range because, it heats up only at the top and the efficiency is very high and they left no residue as waste.
The electric ranges are very smooth and frictionless surface & it is easy to clean. After that the new technology came which is for the professional kitchens. The technology is of induction-based stoves called induction stoves.

The heat which is generated in the induction stoves is due to the electromagnetic induction and in these stoves, we use the utensils having bottom of ferromagnetic substances.

Electric ranges are very famous in urban & rural areas. Electric range is more efficient than gas ranges. The electric range helps us in saving time, it cooks very fast and in more quantity food as compared to the gas stoves. All-electric range is the driving range of a vehicle using only power from its electric battery pack to traverse a given driving cycle

parts of a circle

Let us learn about parts of a circle.

Radius, Diameter, Chord, Secant line, Tangent line,

To find diameter of circle we need to us this formula = D = 2r or r = (1/2)d

Find the diameter of the circle whose radius is 4 cm.
Solution:
Formula: d = 2r
To find: diameter of the circle.
d = 2*r = 2*4 = 8 cm.

how i survived middle school

Surviving Middle School: Tips For Parents From A Middle School Counselor
Hi Friends!!!

How many of you like school days?

The thought of middle school days always brings back spe­cial mem­o­ries. A lovely & cool atmosphere with lots of fun activities. I remember how I survived middle school when ever I see children going school. My school days have become sweet memories of my life. You and your child can enjoy these middle school years only if you:
• Help them to build a sense of self-confidence.
• help them to understand their needs & allow them to spend time with friends.
• Stay firm but flexible when ever necessary.
• And most important is, always keep the lines of communication open.
I can say college life is golden life, lower school is silver life and middle school is diamond life.
Middle school can be ever challenging time in a student's life.

online math tutor

Hi Friends!!!

Let us know how online math tutor will help you to solve past papers.


Practicing maths past papers is the best way to gain perfection in subject and to complete your revision as you can test yourself under exam conditions, with the same three hour time constraint you'll have in the exam. I can say they are the most valuable resource for carrying out revision. Solving past papers enable students to gauge their subject knowledge and uncover their strengths and weaknesses, enabling you to understand what areas you need to devote more time to and conversely, what areas you can devote less time to. Through online math tutoring you can solve past papers.
It is the one of the most effective & easy way of increasing interest in learning and your chances of passing exams at school is to obtain past Test papers.
There are 4 to solve maths past papers:
1. It enables you to understand & establish the type of questions being asked.
2. How those questions will be marked. For exam some answers carry more points then others
3. You will learn how to manage your time during the exam.
4. It helps you to revise & review information from math books or math notes that are most important for the math exam.
One hand before you obtain past papers the better as it enables you to gear your revision around the typical type of questions that you are likely to get asked. online math tutor will help you to solve math past papers.

equilateral triangle

Hi Friends!!!

Can you identify which is the equilateral triangle from given figures.


A triangle in which all three sides are equal or balanced is called an equilateral triangle.

Equilateral triangles are also equiangular; that is, all three internecine angles are also congruent to apiece else and are apiece 60°. They are routine polygons, and can thus also be referred to as regular triangles.



The altitude h of an equilateral triangle is
h=s sin 60 degree
=1/2(√ 3)*a

area of a circle

Let us learn about area of a circle formula


The area of a circle is the number of square units inside that circle.
A circle is a closed smooth curve, each point on the boundary of which is equidistant from a fixed point inside it which is called the centre
Area is the measure of surface occupied by an object. The standard unit for measurement of area is meter square (m2).However the area of smaller dimensions can be expressed in mm2 or cm2. The areas of large dimensions can be expressed in acre or hectare
area of a circle examples
Finding the area of circle with radius equal to 6.5 inch using π = 3.14
Solution:The Area of circle as, A=πr2
Substitute the values of radius and π.
Therefore, A= (3.14 * 6.5*6.5)
Squaring the radius and then multiplying with 3.14 and then we get,
Area=3.14 * 42.25
answers to area of circle = =132.67 square inch.
