8.7 The student will investigate and solve practical problems involving volume and surface area of cones.
1.Find the volume and surface area for 5 different cones.
2. Find the missing dimesion. Round to the nearest unit.
a. Cone: volume 424 cubic meters, diameter 18 meters, height ___
b. Cone: surface area 153.5 sq in, radius 4 in, slant height ___
3. Plants: A cone-shaped paper cup is 7 cm high with a diameter of 6 cm. If the ivy plant on Julia's desk needs 240mL of water, about how many paper cups of water will she use to water it? (1 mL = 1 cubic cm)
