Question

What is the approximate area of a circle whose diameter is 12 cm?

Answer 1

Area= ¶r^2 = 3.14*(12/2)^2 = 3.14*36 ≈ 113.04

Answer 2

In this question , we have to use the formula of area of circle , which is

$Area = \pi r^2$

Where r is the radius .

In the question we have diameter=12 cm, and radius is half of diameter.

So radius =6 cm .

Substituting the value of r and using pi =3.14, we will get

$Area= 3.14*6^2 = 3.14*36 = 113.04cm^2$

So the correct option is the second option .
