I don't have a calculator in front of me but the answerer is.
The area of a circle equation is 2 X Pie X r squared.
Just insert 2 ( the radius of the circle) and run the equation.

the area of a circle is defined as 3.14 times the radius squared so, since the radius is 2 inches you square which will be 4 and multiply by 3.14

Area = pi * radius ^ 2
Area = pi * 2^2
Area = 4 * pi (approximately 12.5663706 square inches)

(2 squared) x 22/7

= 4 x 22/7

= 88/7

Area= 4pi
multiply the radius by the radius.
2x2=4
then 4x3.14 (pi)

A = pi(r^2)

if r = 2

A = pi(2^2)

A = 4pi

Do pi * (radius squared)...

3.14 * (2*2)

3.14 * 4

A = 12.56
