Question

Two similar cones are height of 2cm and 6cm.if the radius of the shorter cone is 3cm, what is the radius of the longer one.

Answer 1

volume of both cone is same

Step-by-step explanation:

• volume of short cone=volume of big cone
• [tex]\frac{\pi r^{2} h}{3}= \frac{\pi R^{2}H }{3} \\ 3^{2}2 = R^{2} 6\\ 9*2=R^{2} *6\\ R^{2} =3\\ R=1.73[/tex]
