Area of a circle equation:
A=(3.14)r^2
40(3.14)=(3.14)*r^2
40=r^2
r= square root of 40
simplified radius is 2 times root 10
(See the photo I attached for the work)
The volume of a cylinder can be calculated by the product of the area of the base times the height of the shape. It is expressed as follows:
V = πr²h
We calculate as follows:
320π in³= π (r²) (5 in)
64 in² = r²
r = 8 in
Hope this answers the question. Have a nice day.
