Answer:
12
Step-by-step explanation:

r - radius, h - height
The diameter is twice the radius.

The answer is c. 791.3 m³.
Answer:
(2A)/h -a =b
Step-by-step explanation:
A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.
2A=h(a+b) Multiply both sides of equation by 2
(2A)/h= a+b Divide both side by h
(2A)/h -a= b Subtract a from both sides
Answer:
I think its supliment but I took this class a long time ago so don't quote me on that
Step-by-step explanation:
Answer: C≈62.83ft
Step-by-step explanation:
