Answer 2

@campbell_st can you help me with this one please?

Answer 3

i think it's 75 cubic ft @campbell_st

Answer 4

ok... to the volume of a cylinder is

\[V= \pi r^2 h\]

volume of a cone is

\[V = \frac{1}{3} \pi r^2 h\]

so for the same measurements, the cone is 1/3 the volume...

so if you know the volume of the cone, multiply the volume by 3 to get the cylinder.

Answer 5

well done.... that's a great answer
