Question

A cylinder has a volume of 375 cubic centimeters. The radius of the cylinder is 12.5 centimeters. What is the approximate height of the cylinder? Use 3.14 for

π
.

A.
9.6 centimeters

B.
7.5 centimeters

C.
2.4 centimeters

D.
0.8 centimeters

Answer 1

D. 0.8

Explanation:

The formula for finding the volume of cylinders is:

V= (pi)(r^2)(h)

r is the radius and h is the height. V is the volume.

plug in the values.

375 = (3.14)(12.5^2)(h)

375 = (3.14)(156.25)(h)

375 = 490.625 x h

Divide both sides of the equation by 490.625

0.7643... = h

round the decimal to the tenths place and get 0.8

Answer 2

0.8 would be the approximate height

Explanation:

you can make an equation and solve for the height (x)

375 = 3.14(12.5^2)x

when you solve this equation, you specifically get 0.76. but your question is asking for the approximate, so you would round it up to 0.8. hope this helps!
