Answer:

154 square cm (choice B)

Step-by-step explanation:

The diameter is 14 cm, so the radius is half that at 7 cm. Let r = 7

Use the formula

A = pi*r^2

to find the area of the circle. Let pi = 3.14 be the approximation for pi

So,

A = pi*r^2

A = 3.14*7^2

A = 3.14*49

A = 153.86

A = 154
