Question

A cylinder has a radius of 4.5 cm and height 19 cm. What is the surface area of the cylinder in terms of π? Apply the formula SA = 2B + Ph

Answer 1

x-1 or (-1, 2) y=2

Explanation:

Step 1- simplify every equation

1x=1-y

1y-x=3

Step 2- substitute 1-y for x in equation 2

y-(1-y)=3

2y=4

y=2

Step 3- substitute 2 for y in equation 1

x=1-2= -1

so, the solution is x= -1 or (-1, 2)

y=2

Hope this helps!

Answer 2

The answer is 664.45
