Find the volume of a right cylinder that has a diameter of 10m and a height of 27m. use 3.14 for pi and round to the nearest whole meter.

Answer 1

V= hA = hpir^2 = h(pi)(d/2)^2 = 10(3.14)(5)^2 =785 m^3

Volume = height times pi times the radius squared

If you used a more precise value for pi, 3.14159, you'd get 785.4 m^3

but either way, rounded off to nearest meter gives 785 cubic meters.
