Question

Find the radius of the cylinder when volume is 304 cm^3 and height is 10 cm

Answer 1

3.11 cm

solution,

Volume of cylinder=304 cm^3

height=10 cm

Radius=?

Now,

`volume = \pi {r}^(2) h \\ or \: 304 = 3.14 * {r}^(2) * 10 \\ or \: 304 = 31.4 * {r}^(2) \\ or \: {r}^(2) = (304)/(31.4) \\ or \: {r}^(2) = 9.68 \\ or \: r = √(9.68) \\ or \: r = \sqrt{ {(3.11)}^(2) } \\ r = 3.11 \: cm`

Hope this helps..

Good luck on your assignment..
