As part of a community clean-up project, several artists are painting murals on cylindrical trash cans. Each trash can has a height of 4 feet and a radius of 1.8 feet, and each mural completely covers the lateral side of a trash can.

About how much area does each mural cover?

    The lateral surface area of a cylinder is:

    a=2πrh, we are told that r=1.8ft and h=4ft so

    a=2π (1.8*4)

    a=2π (7.2)

    a=14.4π ft^2

    a≈45.24 ft^2 (to nearest hundredth of a square foot)
