Rotary cone

Rotary cone whose height is equal to the circumference of the base, has a volume 229 cm3.

Calculate the radius of the base circle and height of the cone.

Correct answer:

r =  3.26 cm
h =  20.51 cm

Step-by-step explanation:

V=13πr2h=229 cm3 h=2πr  V=23π2r3  r=32Vπ23=3.26 cm
h=2πr=20.51 cm
