Question

FIND THE AREA OF A CIRCLE WHOSE RADIUS IS 7CM

Answer 1

Area of the Circle = πr² [pie(π) multiplies to radius (r) square]

π = 22/7 or 3.14

As Given, The Radius is 7 cm.

Applying Formulae — π (7)²

= 22/7 * 7 * 7.

= 22*7.

= 154cm²

or

( putting value of π as 3.14 )

= 3.14 * 7 * 7

= 21.98 * 7

= 154cm².

Hence, The area of the circle is 154cm².

Answer 2

Answer:

154 cm²

Step-by-step explanation:

Given:-

Radius of the Circle= 7 cm

To Find:-

Area of the Circle.

Formula Used:-

Area of the Circle=πr²,where r is the radius of the circle and π =$\frac{22}{7}$

Solution:-

Area of the Circle=πr²=$\frac{22}{7}$×7×7=22×7= 154 cm²
