the circle at eh top of a cylinder has a radius of 3.3 inches. the cylinder is 21 inches long. what is the volume of the cylinde
r?
1 answer:
Answer:
V =718.0866 in^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The radius is 3.3 and the height is 21
V = pi (3.3)^2 * 21
V = pi (10.89) (21)
V =pi 228.69
We can approximate pi by 3.14
V = 3.14(228.69)
V =718.0866 in^3

Length: w+4
Width:w
Perimeter:44
Area: L times w
P=44
44=2(w)+2(w+4)
44=2w+2w+8
44=4w+8
36=4w
w=9
L=w+4
L=9+4
L=13
Area should equal 117 cm squared
