Answer:
31
Step-by-step explanation:

25.13cm^2 or 8pi. The radius of a circle is 2 x pi x r^2. R is the radius. 2 x pi x 2^2cm -> 2 x pi x 4cm -> 8cm x pi -> 25.13cm^2. Leaving the answer in terms of pi would be 8pi.
Answer:
360 in ^3
Step-by-step explanation:
The volume is given by
V = l*w*h
= 8 * 5 * 9
= 360 in ^3
