Question

What is the volume of a right circular cylinder with a radius of 3 in and a height of 10 in

Answer 1

4.64$cm^{3}$

Step-by-step explanation:

$r= 3in$

1 inch= 2.54 m

$r= 3\times 2.54cm$

 $=7.62cm$

and similarly,

$h=10\times 2.54cm$

  $=25.4cm$

so, volume of the cylinder

$V=\pi r^{2}h$

$V=\frac{22}{7}\times (7.62)^{2}\times 25.4$

$V=\frac{22}{7}\times 58.1\times 25.4$

$V=4635.2cm^{3}$
