Answer:
235.5 cubic inches
Step-by-step explanation:
The volume of a cylinder is found using the volume formula
.
Substitute h=3 and r = 5.

It will take her about 17 minutes because of gravity within the radius
They will go over point 3,0 and /4,9 then
You essentially have four triangles. The area of a triangle is: A=bh/2 (b=base length and h=height)
So the area is simply the sum of the four triangle areas...
A=(3*2)/2+(3*2)/2+(7*2)/2+(7*2)/2
A=20 ft^2
