The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot. Show your work.
this is my answer
surface area:
A=2*π*r*h + 2*π*r^2
volume:
V=π*r^2*h
just plug in the numbers.
surface area:
A=2*π*3.5*14 + 2*π*3.5^2
A=154.2 ft^2
volume:
V=π*3.5^2*14
V=611.8 ft^3
