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

$791.68 = 2* \pi * 9^2 + 2 * \pi * 9*h
\\
791.68 = 162 \pi + 18 \pi h
\\
791.68 -162 \pi = 18 \pi h
\\
h = \frac{791.68 -162 \pi}{18 \pi}
\\
h =5 units$

So the height of the cylinder is 5 units .

11111nata11111 [884]

Answer:

a. y = (3/5)× x +1

Step-by-step explanation:

y= mx+c

m = (13-4)/(20-5) = 9/15 = 3/5

c= 1

so, y= mx+c becomes y= (3/5) × x +1
