Answer:
2976 in³
Step-by-step explanation:
Stool volume = upper smaller prism + Lower bigger prism
Stool volume = 8 x 6 x 12 + 20 x 12 x 10 = 576 + 2400 = 2976
check: volume = 20 x 12 x 16 - 12 x 12 x 6 = 2976
Area= 2πr
So,
If you were to multiply the radius by 2 since 2 is not in the equations,
4*2= 8
8π ft^2 would be the correct answer.
I hope this helps!
