Answer:
D
Step-by-step explanation:
Circumference of circle = 2πr
r = 9cm
Circumference of circle = 2×9×3.142
Circumference of circle = 56.5cm
The answer is C. 89 in^2
This is found by (1/2(

))+70
r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5
You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.
Hope this helps!
