Question

For brett's birthday his mother gave out colorful birthday hats that were cone shaped. the opening of the bottom of the hat was 3 cm and the height of the cone was 7 cm. brett filled his hat with candy. what is the approximate volume of candy?

Answer 1

The volume of cone is calculated by the formula
`V= (1)/(3) \pi R^2H`, where H is a height of cone and R is a radius of the bottom.
In your case, R=3 cm and R=7 cm. Then
`V= (1)/(3) \pi* 3^2*7= (63\pi)/(3) =21\pi`.
Answer: The volume of candy is 21π.
