Answer:
A=640.88
Step-by-step explanation:
if the diameter is 12, the radius , r=12/2=6
we have r=6, h=11
Surface area, A= 2πrh+2π r^2
A=2*3.14*6*11+2*3.14*(6)^2=640.88
Answer:
b
Step-by-step explanation:
=a^1/x=x√a
(a^1/x) ^b= x√a^b
A) 1.5, you can cross off C and D because that's area. the only reasonable would be 1.5 and 5.8. But 5.8 would mean cutting half of the board.
First we need to find the square footage of her ceiling, since it's a square just multiply the side by the side: 44•44=1936. Now divide the square feet by how many feet each can can paint: 1936/242=8. Jenny would need exactly 8 cans of paint to paint her ceiling :)
