Question

find the area of a circle whose radius is 5 cm

Answer 1

Area of circle =πr2
22/7*5*5
=> 78.57 is your answer.

Answer 2

Given:

A circle has a radius of 5 cm.

To Find:

The area of the circle is?

Solution:

The given problem can be solved using the formulae of circles.

1. The radius of the circle is 5cm.

=> Radius of the circle = 56cm.

2. Area of a circle is given by the formula,

=> Area of a circle = πxr²,

3. Substitute the value of r to find the area,

=> Area of the circle = (22/7) x 5 x 5,

=> Area of the circle = (22/7) x 25,

=> Area of the circle = 78.57 cm².

Therefore, the area of the given circle is 78.57 cm².
