The radius of a cylinder is 7.8*10^-4 m. the height of the cylinder is 3.4*10^-2 m. what is the volume? write in scientific notation.

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume of cylinder = πr^2h

Where

π is a constant whose value is 3.14.

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

The radius of a cylinder is 7.8*10^-4 m.

The height of the cylinder is 3.4*10^-2.

Therefore,

Volume of cylinder =

3.14 × (7.8*10^-4)^2 × 3.4*10^-2

= 3.14 × 60.8*10^-8 × 3.4*10^-2

= 649.52784 × 10^- 10 m^2

42.4
