The cylinder and rectangular prism below both have a height of 9 inches and a volume of 452.39in^3. a. What is the area of the base of each object?

b. What is the radius of the cylinder?

c. If the rectangular prism has a width of 5.8 inches what is it's length?

a) Area of base of cylinder =

Area of base of prism = 50.265 sq.in.

b)Radius of cylinder = 3.99 in

c)If the rectangular prism has a width of 5.8 inches so. length is 8.66 in

Step-by-step explanation:

Volume of cylinder =

Height of cylinder = 9 inches

We are given that the volume of cylinder is

Area of base of cylinder =

Volume of prism =

Height of prism = 9 inches

Volume of prism =

So,

Area of base of prism = 50.265

Width of prism = 5.8

So,

a) Area of base of cylinder =

Area of base of prism = 50.265

b)Radius of cylinder = 3.99 in

c)If the rectangular prism has a width of 5.8 inches so. length is 8.66 in

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
