Question

Find the volume of this cone.Use 3 for TT.4 cmV ==Tir2h3Hint: The radius (l) is1/2 of the diameter.18 cmV ~ [?]cm3

Answer 1

From the figure,

The height is h=8 cm.

The diamaeter is d=4 cm.

The radius is r=d/2=2 cm.

We know,

The volume is given by:

`V=\frac{\pi^{}^{}}{3}r^2h\text{ }`

Putting the value,

`V=(3*2^2*8)/(3)=32\text{cubic cm}`

The answer is 32 cubic cm.
