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)
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)
The area does each mural cover 54.24 feet square.
We have given that,
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.
The lateral surface area of a cylinder is,
What is the formula for the lateral surface area?
A=2πrh,
We are told that r=1.8ft and h=4ft so
[tex]A=2\pi (1.8*4)[/tex]
[tex]A=2\pi (7.2)[/tex]
[tex]A=14.4\pi ft^2[/tex]
[tex]A=54.24 ft^2[/tex] (to nearest hundredth of a square foot)
