Answer 1

Emily needs to make party hats in the shape of a cone. She

wants the hat to have a radius of 6 inches and a height of

15 inches. What is the volume of the party hat?

a) 565.2

b) 94.2

c) 2260.8

d) 188.4

the volume of a cone is equal to

`V=(1)/(3)\cdot\pi\cdot r^2\cdot h`

we have

pi=3.14

r=6 in

h=15 in

substitute

`\begin{gathered} V=(1)/(3)\cdot3.14\cdot6^2\cdot15 \\ V=565.2\text{ in3} \end{gathered}`

answer is option A
