Bill used candle molds, as shown, to make candles that were perfect cylinders and spheres:

What is the approximate difference in the amount of wax needed to make a candle from each of these molds? (Use π = 3.14.)

21.0 cubic inches
28.26 cubic inches
52.55 cubic inches
66.0 cubic inches

Answer 1

volume cylinder

=3.14×3^2×5

=141.3 cubic inches

volume sphere

=4/3×3.14×3^3

=113.04 cubic inches

difference between volume of cylinder and sphere

=141.3-113.04

=28.26 cubic inches
