Question

Jim Juice treats that are in the shape of a cone. The molds he bought are each 3 inches (in.) deep with a diameter of 3 in. What is the approximate volume of juice needed for Jim to make 6 juice treats?

A.169.6 in
B.127.2 in
C.84.8 in
D.42.4 in

Answer 1

Option D.
`42.4\ in^(3)`

Explanation:

we know that

The volume of the cone (juice treats) is equal to

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

we have

`r=3/2=1.5\ in` ----> the radius is half the diameter

`h=3\ in`

assume

`\pi=3.14`

substitute

`V=(1)/(3)(3.14)(1.5)^(2)(3)=7.065\ in^(3)`

Multiply the volume of one juice treats by 6

`(6)7.065=42.39=42.4\ in^(3)`
