Cylinder area=height times area of base (area of base=area of circle)
height =1.8
radius=6.1
area of circle=pi times r^2
area of circle=pi times 6.1^2=37.21π
times height
1.8 times 37.21π=66.978π
volume=66.978π ft^3
Answer:
40
Step-by-step explanation:
by using similar triangles;
27/24=45/x
x=45x24/27=40
(x + 9)(x + 12) = 0
Expanding the brackets, we get:
