Answer:

A: 113.04in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We know the diameter is 12 inches so the radius is 1/2 the diameter

r = 1/2 d =1/2(12) = 6inches

A = (3.14) (6)^2

A = 113.04 in ^2

Answer:

A. 113.04 in^2

Step-by-step explanation:

A = πr^2 where r is the radius of the circle

Radius = diameter/2

Radius = 12/2

Radius = 6

A = π(6)^2

A = π(36)

A = 113.04
