Question

the circumference of the base of a right circular cone is 22 CM. If the height be 8 CM. find the value.

Answer 1

answer is right or wrong

Answer 2

The volume of the cone is 102.66 cm³.

Step-by-step explanation:

Given : The circumference of the base of a right circular cone is 22 cm. If the height be 8 cm.

To find : The volume of cone ?

Solution :

Circumference of the base of cylinder is

$C=2\pi r$

$22=2\times \frac{22}{7}\times r$

$r=\frac{22\times 7}{2\times 22}$

$r=3.5$

The radius is 3.5 cm.

Volume of a cylinder is given by,

$V=\frac{1}{3}\pi r^2h$

$V=\frac{1}{3}\times \frac{22}{7}\times (3.5)^2\times 8$

$V=\frac{1}{3}\times \frac{22}{7}\times 12.25\times 8$

$V=102.66\ cm^3$

Therefore, the volume is 102.66 cm³.
