A metal cylindrical cannister is 1' 3"long and has a diameter of 4 inches. What is the total surface area of the cylinder?
Answered by Kleena
A=2πrh+2πr2
radius=2 (d/2)
h=1.3
A=41.47
Double check this. :)
Answered by Steve
h = 15 inches, not 1.3
Answered by Daria
1’3” = 15 inches & Radius = 2 in
SA = 2πr² + 2πrh
= 2 (π) (2²) + 2 (π) (2) (15)
= 213.63in²
