Question

The formula for finding the volume of a cone is v = 13πr2h. the volume of a cone is 300 cm3 and the height of the cone is 10 cm. what is the approximate radius of the cone?

Answer 1

just answered the question. the correct answer is h=3v/πr2

Answer 2

V=
`(1)/(3) \pi r^(2) h`
V=300
h=10cm
300=
`(1)/(3) \pi r^(2)*10`

`r^(2) = (300*3)/(10 \pi ) r^(2) = (900)/(31.42) r^(2) =28.65 r= √(28.65) r=5.352`
