Question

The area of cone base is 64π cm^2 and slant height is17cm, then cone remolded to solid sphere. The radius of sphere is

Answer 1

Answer:

Step-by-step explanation:

Answer 2

l=17cm

$\pi {r}^{2} = 64 {cm}^{2}$

r of cone=8cm

${l }^{2} = {r}^{2} + {h}^{2}$

$289 = 64 + {h}^{2}$

h= 15 cm

$\frac{1}{3} \pi {r}^{2} h = \frac{4}{3} \pi {r}^{3}$

${r}^{3} = 240$

$r = \sqrt[3]{240}$

r=6.21cm
