What is the volume of a cylinder with height of 9 inches and the the radius is 1 inch. round to the nearest cubic inch

Step-by-step explanation:

Volume of cylinder can be calculated by using the formula V= pir^2h

Where r is radius of cylinder and h is the height.

A cylinder with radius 1 inch and height of 9 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=πr2h=π·12·9≈28.27433

Volume of cylinder rounded to nearest tenth is 28.27 cubic inches .

K=xy

Step-by-step explanation:

In the inverse variation function where x varies inversely as y, x=k/y but making k the subject k=x(y)
