Question

a pillar candle is shaped like a cylinder with a radius of 1.5 inches. The candle hold 123 cubic inches of wax. How tall is the candle? Use 3.14 for pie. Round your answer to the nearest hundredth.

Answer 1

212.54

Explanation:

Find the radius

4.75/2 = 2.375

v = pi r ^2 h

v = (3.14) (2.375)^2 (12)

v = (3.14) (5.64) (12)

v = 212.54

Answer 2

h=17.4 so basically you plug in what you have in the formula for finding the volume of a cylinder which is V=pi
`r^(2)` xh r being radius and h height so it would be 123=pi
`1.5^(2)` xh then you solve like an equation
