X=1, y=4

Substitute 4x in for y in the second equation and you get 5x=5. Divide out 5 and you get x=1. Then, you can plug 1 in for x into either equation and solve for y.

Find the altitude of a cylinder with with a radius of 9 and a surface area of approximately 791.68 units2.
Vika [28.1K]

In this question , it is given that we have a cylinder with with a radius of 9 and a surface area of approximately 791.68 units square.

The formula of surface area of cylinder is

A= 2 \pi r^2 + 2 \pi r h

Substituting the values of A and r, we will get

791.68 = 2* \pi * 9^2  + 2 * \pi * 9*h&#10;\\&#10;791.68 = 162 \pi + 18 \pi h&#10;\\&#10;791.68 -162 \pi = 18 \pi h&#10;\\&#10;h = \frac{791.68 -162 \pi}{18 \pi}&#10;\\&#10;h =5 units

So the height of the cylinder is 5 units .
