Question

Check my answer plz.

A right cylinder has a diameter of 50 mm and a height of 40 mm as shown.

What is the volume of the cylinder?



A.
314,000 mm3

B.
78,500 mm3

>>C.
25,000 mm3

D.
6280 mm3

Answer 1

the formula for volume for a Cylinder is V=(pi) r^2 h
where:
r= radius
h= height
if the diameter is 50mm you would need to 1/2 that to get your radius which would be
50 x 1/2=25mm
the height is 40
plug both these numbers in the equation to get:
V=(pi) (25)^2 (40)
simplify
V=78,539.8163397mm^3
round that to 78,500mm^3
hope this helps!
