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=$\frac{1}{3} \pi r^{2} h$
V=300
h=10cm
300=$\frac{1}{3} \pi r^{2}*10$
$r^{2} = \frac{300*3}{10 \pi } r^{2} = \frac{900}{31.42} r^{2} =28.65 r= \sqrt{28.65} r=5.352$
