Answer 2

Answer:

The area of a circle whose radius is 12 is 452.16

Step-by-step explanation:

A circle whose radius is 12.

formula:-

Area of the circle = $\pi r^{2}$

Put the value of r in the formula.

So the area of circle = $\pi r^{2}$

         value of $\pi$ = 3.14

         value of r = 12

Area of circle = 3.14 x 12 x 12

                       = 3.14 x 144

Area of circle  = 452.16
