The volume of a cylinder is 289pi in.cubed and the height of the cylinder is 1 in. What is the radius of the​ cylinder?

Answers

The radius of the cylinder is 17 inches.

Step-by-step explanation:

Given,

Volume of cylinder = V = 289π  in cubed

Height of cylinder = h = 1 in

Radius of cylinder = r

We know that;

Volume of cylinder = πr²h

Putting values;

289\pi =\pi r^2(1)

Dividing both sides by π (pi)

(289\pi )/(\pi )=(\pi r^2)/(\pi )

289=r^2\nr^2=289

Taking square root on both sides

√(r^2) =√(289) \nr=17\ in.

The radius of the cylinder is 17 inches.

Is (0,2),(1,4), (2,5), (3,6) a function

Answers

Answer:

This relationship is a function

Step-by-step explanation:

By definition a relation is defined as a function if and only if for each input value x there is only one output value y.

In this case we observe the following ordered pairs

(0,2),(1,4), (2,5), (3,6)

We see that each value x has only a value of y.

x = 0,\ y = 2\n\nx = 1,\ y = 4\n\nx = 2,\ y = 5\n\nx = 3,\ y = 6

Therefore this relationship is a function
