Question

If a metallic cylinder having volume 1540 cm^3 is melted to form cylinder having height 10 cm what is radius of cylinder​

Answer 1

radius is 7 cm

Explanation:

formular for volume:

`V = \pi {r}^(2) h`

r is radius

h is height

`1540 = 3.14 * {r}^(2) * 10 \\ {r}^(2) = 49.0 \\ r = 7 \: cm`
