Question

Help me with my maths volume skills peer

Answer 1

3591.3

Explanation:

`r = (19)/(2) \\ \\ vol = (4)/(3) \pi {r}^(3) = (4)/(3) * 3.14 * {( (19)/(2) )}^(3) \\ \\ (4)/(3) * 3.14 * 857.37 = 3591.36`

Answer 2

• Radius=Diameter/2=19/2=9.5cm

Volume:-

`\\ \rm\Rrightarrow (4)/(3)(pi)(9.5)^3`

`\\ \rm\Rrightarrow 4/3(/pi)(857.4)`

`\\ \rm\Rrightarrow 1143.2\pi cm ^3`
