Answer:
Option B. ![11.78\ in^{3}](https://tex.z-dn.net/?f=11.78%5C%20in%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cone is equal to
![V=\frac{1}{3} \pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E%7B2%7Dh)
we have
![r=1.5\ in](https://tex.z-dn.net/?f=r%3D1.5%5C%20in)
![h=5\ in](https://tex.z-dn.net/?f=h%3D5%5C%20in)
substitute
![V=\frac{1}{3} \pi (1.5)^{2}(5)](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%281.5%29%5E%7B2%7D%285%29)
![V=3.75\pi\ in^{3}](https://tex.z-dn.net/?f=V%3D3.75%5Cpi%5C%20in%5E%7B3%7D)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
![V=3.75(3.14)=11.78\ in^{3}](https://tex.z-dn.net/?f=V%3D3.75%283.14%29%3D11.78%5C%20in%5E%7B3%7D)
Given:
grapes = 2 1/2 pounds
apples = 1 1/4 times as many pounds as grapes.
For easier computation, let us convert these fractions into numbers with decimal places.
2 1/2 pounds = 2.50 pounds
1 1/4 times = 1.25
Apples = 2.50 pounds * 1.25 = 3.125 pounds of apples.
Or we still use fractions. We need to convert the mixed fractions into improper fractions.
2 1/2 = 5/2
1 1/4 = 5/4
5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds
