PLEASE HELP ME WITH MY HOMEWORK!

Determine the area of a circle whose diameter is 15 inches. Use 3.14 for π. Round to the nearest tenth.

A. 47.1 in squared
B. 706.5 in squared
C. 94.2 in squared
D. 176.6 in squared

Answer 1

the anwser to this is d

Answer 2

aera=pi*radius^2

diameter/2=radius

given tat diameter=15

iameter/2=15/2=7.5=radius

area=pi*radius^2=3.14*7.5^2=3.14*7.5*7.5=176.625 in^2

so answer is D
