Question

Can u help solve this

Answer 1

Explanation:

`volume = (4)/(3) \pi \: {r}^(3) \\ = here\pi = 3 \\ then \: v = (4)/(3) * 3 * {5}^(3) \\ = 4 * 125 \\ = 500 {in}^(3) \\ thank \: you`

Answer 2

Sure:)! the answer is-487.5

Explanation:

1. 1.3x3xr^3
2. 1.3x3=3.9
3. 3.9r^3
4. r=5
5. 5x5x5=125
6. 3.9x125=487.5

As said in the problem pie=3 as determined in the problem. Hence, the answer is 487.5

Hope this helps :)!
