Find the difference in the volume and total area of a cylinder with both a radius and height of 1. r = 1, h = 1 the number of sq units of the total area exceeds the number of cu. units in the volume by 3π 2π π

The difference in the volume of cylinder and total surface area of cylinder =.

The number of sq units of total area exceeds the number of cu.units in the volume .

Step-by-step explanation:

Given radius of cylinder =1 unit

Height of cylinder= 1 unit

We know that  formula of volume of cylinder =

Where r= Radius of  the cylinder

            h= Height of the cylinder

By using this formula  we can  find the volume of cylinder

 volume of cylinder = =

By using this formula we can find total surface area of cylinder

 Total surface area of cylinder = sq units .

Difference between volume of  cylinder and total surface  area of cylinde= =

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
