Answer:
1243 ft³
Explanation:
Given the volume formula for a cylinder:

and we know that the radius is 6 and the height is 11, we can substitute:

square 6
V=π36(11)
use 3.14 for pi and multiply everything together
V=3.14(36)(11)
simplify
V=1243.44
1243.44 rounded to the nearest whole number is 1,243 ft³.
