Answer:

V = 565.5

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)
