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.

Respuesta :

volume of candle = 3.24 * r^2* h    where r = radius and h = height

so plugging in the given values:-

123 = 3.14 * 1.5^2 * h

h = 123 / ( 3.14* 1.5^2)
  
  =  17.41 inches to nearest hundredth

apologiabiology
v=hpir^2
pi=3.14
h=h
v=123
r=1.5

123=h3.14*1.5^2
123=h3.14*2.25pi
123=h7.065pi
divide both sides by 7.065
17.409=h
round to hundreth
17.41 inches
