Question

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

Answers

  1. The formula to find surface area of a cylinder is A = 2(pi)rh + 2(pi)r^2
    So :
    A = 2 (3.14) (3.5ft)(14ft) + 2(3.14) (3.5ft)^2
    A = 307.72 + 76.93
    A = 384.65 ft^2
    Rounded to the nearest tenth : 384.7 ft^2

    Volume of a cylinder is : (pi)r^2h
    V = (3.14)(3.5ft)^2 x (14ft)
    V= 538.51 ft^3
    Rounded to the nearest tenth: 538.5 ft^3
