Answer:
156
Step-by-step explanation:
13 x 12 = 156
V= 1/3 pi r^2h
Find the radius
r=d/2
r=8/2
r= 4
V= 1/3 pi (4)^2•6
V=32pi or 100.53
Answer:
To find the area of a circle you use the formula 
r is the radius so plug that in.
if you only have the diameter, just divide that number by 2 to get the radius
