If someone can do this whole thing for me I will give brainiest.

A= x r^2

A= x r x r

r means radius

The value of pi() is 3.14

r^2 means radius x radius

Substitute the radius for r: A= x 7^2

Square the radius: 7 x 7= 49

Area in terms of pi(): 49

Area in terms of square inches: 153.86 in^2

Divide the diameter by 2: 12 ÷ 2= 6

Substitute the radius for r: A= x 6^2

Square the radius: 6 x 6= 36

Area in terms of pi(): 36

Area in terms of square inches: 113.04 in^2
