Question

What is the height of a cylinder with a volume of 1,899.7 cubic inches and a radius of 11 inches? (Use 3.14 for π.)

5 inches
6 inches
7 inches
8 inches

Answer 1

you need the formula for the volume of a cylinder. When you write it down, you will see that the statement gives the value of all quantities except "h" the height.

Answer 2

what is the formula?

Answer 3

\(V = \pi r^2 h \)
where \(V=\) volume, \(r=\) radius, \(h=\) height.

Answer 4

u can use a calculator?
then 1889.7/(3.14 * 11^2) = 4.99.. = 5 (approx.)

Answer 5

so would it be 502.4 ft^2 at least that is what i got

Answer 6

your answer is not for "h"..?

Answer 7

sorry i was looking at the wrong problem sorry hold on

Answer 8

ok haha no problem.

Answer 9

um 7 inches....? sorry i am really bad at math

Answer 10

Forom the formula above, if you want to find \(h\), use \(\frac{V}{\pi r^2} = h\).
V = 1899.7, pi = 3.14, r = 11. the answer's not 7.

Answer 11

5 right?

Answer 12

yep

Answer 13

thank u so much for ur help!!!!
