Question

What is the volume, in cubic cm, of a cylinder with a height of 8cm and a base radius of 7cm, to the nearest tenths place?

Answer 1

Answer:

Volume of the cylinder =  $1230.88\,cm^3$

Step-by-step explanation:

Height(h) of the cylinder = $8 cm$

Radius(r) of the base= $7cm$

Volume of a cylinder is:

                  = $\pi \times r^2\times h$

As,

   $\pi =\dfrac{22}{7} = 3.14$

Putting the values in the formula:

Volume is:

           $=3.14\times(7\times7)\times8\\\\=3.14\times49\times8\\\\=3.14\times392\\\\=1230.88\,cm^3$

The volume of the cylinder is :  $1230.88\,cm^3$
