Answer 1

i agree b

Explanation:

Answer 2

B) 18.8 cubic inches.

Explanation:

Given:

A paper cup in the shape of an inverted cone.

Height = 8 inches

Radius, r = 1.5 inches

We have to find capacity or volume of the inverted cone shaped cup.

Solution:

As we know:

`Volume\ of\ cone=(1)/(3) *\pi r^(2) h`

`=(1)/(3) *3.14* (1.5)^(2) *8\\ \\ =(1)/(3) *3.14*2.25 *8`

`=(56.52)/(3) \\ \\ =18.84\ cubic\ inches`

Volume of cup nearest tenth is 18.8 cubic inches.
