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.
