(06.04 MC) One link in a chain was made from a cylinder that has a radius of 2.5 cm and a height of 22 cm. How much plastic coating would be needed to coat the surface of the chain link? Use 3.14 for π.

(06.01 MC) Jude says that the volume of a square pyramid with base edges of 12 in and a height of 10 in is equal to the volume of a cylinder with a radius of 6.77 in and a height of 10 in. Jude rounded his answers to the nearest whole numbers. Examine Jude’s calculations. Is he correct? Volume of Square Pyramid Volume of Cylinder V = B(h) V = πr2h V = (144)(10) V = π(6.772)(10) V = (1440) π(45.8329)(10) V = 480 in3 V = π(458.329)   V ≈ 480 in3

(06.03 MC) A large emerald with a mass of 812.04 grams was recently discovered in a mine. If the density of the emerald is 2.76, what is the volume? Round to the nearest hundredth when necessary, and only enter numerical values, which can include a decimal point.

(06.01 MC) Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder with a radius of 7 in and a height of 7 in. Jude rounded all answers to the nearest whole number. Examine Jude’s calculations. Is he correct? Volume of Square Pyramid Volume of Cylinder V = B(h) V = r2h V = 49(7) V = (72)(7) V = 343 in3 V = 343 in3

(06.02 MC) A cylindrical piece of iron pipe is shown below. The wall of the pipe is 1.25 inches thick: What is the approximate inside volume of the pipe?

(06.04 LC) If a right triangle was rotated about the y-axis, like the one shown below, what would be the resulting three-dimensional shape?

(06.02 MC) Which combination of shapes can be used to create the 3-D figure?

(06.02 LC) A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 7 marbles, each of diameter 3 inches. The vase is filled with water up to a height of 12 inches. Which of the following could be used to calculate the volume of water in the vase?

(06.03 MC) What is the weight (in grams) of a liquid that exactly fills a 202 milliliter container if the density of the liquid is 0.685? Round to the nearest hundredth when necessary, and only enter numerical values, which can include a decimal point.

(06.01 MC) A triangle has sides that measure 2 units, 5 units, and 5.39 units. What is the area of a circle with a circumference that equals the perimeter of the triangle? Use 3.14 for π, and round your answer to the nearest whole number.
