Question

Dosha is creating a new dessert that has two layers shaped like cones. The inner cone is frozen ice cream and has a diameter of 10 cm and a height of 6 cm. The outer layer is a thin wafer shell, like an upside-down ice cream cone, with a height of 14 cm and the same diameter as the inner layer. Dosha will inject a cream filling into the space.

What is the volume of the cream filling? Round your answer to one decimal place and use 3.14 to approximate pi.

Answer 1

Answer: 1456.33-628=837.3 cm^3

Explanation:

hope this helps

Answer 2

first find volume of inner cone and outer cone then subtract inner from outer

so inner=1/3 (base area) times height
1/3 times (pi times 10^2) times 6
1/3 times 3.14 times 100 times 6
1/3 times 314 times 6
314 times 6/3=628=volume of inner cone

outer cone
base area=314
1/3 times 314 times 14=1456.33

so subtract 628 from 1456.33

1456.33-628=837.3 cm^3
