A.50.24 cubic inches B,28.3 cubic inches C.25.1 cubic inches

What is the volume of wax in the candle shaped like a cone?
A. 50.24 CUBIC FEET b.28.3 cubic feet C.25.1

Answer 1

for problem 8 it would be 28.3

Answer 2

Problem 8

Answer: 28.3 cubic inches

------------------------

Work Shown:

V = pi*r^2*h

V = 3.14*(1.5)^2*4

V = 28.26

V = 28.3

Note how the radius r = 1.5 is half of the diameter 3 inches.

=========================================

Problem 9

Answer: 25.1 cubic inches

------------------------

Work Shown:

V = (1/3)*pi*r^2*h

V = (1/3)*3.14*2^2*6

V = 25.12

V = 25.1
