113.04 cubic inches
56.52 cubic inches
100.34 cubic inches

Answer 1

Please someone help me really need help will give out medals..

Answer 2

\[V = \pi r^2 h\]
r = diameter / 2
h = 9
pi = 3.14

Answer 3

So V=3.14) r^2) 9

Answer 4

and what do I have to multiply here there is no radius?

Answer 5

So if mulitplying without the radius its 56.52 are u sure about that?

Answer 6

diameter = 2* radius

Answer 7

so what is the answer it may be 56/52 or 113.04

Answer 8

A pillar candle is shaped like a cylinder with a radius of 1.5 inches. The candle holds 123 cubic inches of wax. How tall is the candle? Use 3.14 for pi. Round your answer to the nearest hundredth. (4 points)

12.50 inches
17.41 inches
18.76 inches
15.76 inches

Answer 15

Volume = 123 cubic in
radius = 1.5 in
find h
using
\[V = \pi r^2 h\]

Answer 16

v=3.14) 1.5)^2(h)

Answer 17

How can i find the Height?

Answer 18

123 = (3.14)* (1.3)^2 * h
h = 123/ (3.14)*(1.5)^2

Answer 19

so it should be 17.41?

Answer 20
