Question

Find the diameter of cone if its volume is 48 cm with height 9 cm

Answer 1

Answer:

Step-by-step explanation:

Volume of Cone is=$\frac{1}{3}$$\pi r^{2}h$;

Given that Volume is 48;

Height=9;

48=$\frac{1}{3}$*$\pi r^{2}*9$;

by solving this we got;

$r^{2}=\frac{48*3}{3.14*9};\\ r^{2}=\frac{144}{28.76}=5;\\  r=\sqrt{5}$;

r=2.23;

So  diameter=2r=2*2.23=4.47
