Step-by-step explanation:

h=20r=8

Answer:

V = 565.5

Step-by-step explanation:

Cylinder Formulas in terms of r and h

  • Calculate the volume of a cylinder:

V = πr2h

  • Calculate the lateral surface area of a cylinder (just the curved outside):

L = 2πrh

  • Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

  • Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
