105

Question 4

Complete the statements about the two cones. The volumes of the cones are equal when . If a > b, then the cross-sectional area of cone A is the cross-sectional area of cone B at every level parallel to their respective bases.

Selection 1: a = b; Selection 2: greater than

Question 5

It costs the same to produce both packages, so the company wants to reduce the amount of wasted space, or space not taken by the balls. Which package should the company choose?

Revolt · Accepted Answer

the cylinder because it has about 27.5 in.3 less wasted space than the prism

Question 6

Complete the steps to calculate the density of the steel. Calculate the volume of the prism. Recall that the area of a hexagon is times the apothem times the perimeter. V = cm3 Calculate the volume of the cylinder. Round to the nearest hundredth. V = cm3 Find the volume of the composite figure. V = cm3 Calculate the density by dividing the mass by the volume. d = g/cm3

Revolt · Accepted Answer

Calculate the volume of the cylinder. Round to the nearest hundredth. V = cm3: 0.06; Calculate the density by dividing the mass by the volume. d = g/cm3: 7.77
