Question

Help i dont understand these

Answer 1

Number 10. is 523.6, Number 11. is 1436.76, Number 12. is 3053.63, Number 13. 904.78, Number 14. is 113.1, Number 15. is 11494.04.

Explanation:

10. V= 4/3*
`\pi r^(3)`

V= 4/3*3.14*
`5^(3)`

V=523.6

11. V=4/3
`\pi r^(3)` Remember Radius is half a diameter

V=4/3*3.14*
`7^(3)`

V=1436.76

12. V=4/3*
`\pi r^(3)`

V= 4/3*3.14*
`9^(3)`

V=3053.63

13. V=4/3*
`\pi r^(3)`

V=4/3 *3.14*
`6^(3)`

V=904.78

14. V=4/3*
`\pi r^(3)`

V= 4/3*3.14*
`3^3}`

V=113.1

15. V= 4/3
`\pi r^(3)`

V=4/3*3.14*
`14^(3)`

V=11494.04
