Answer:
Step-by-step explanation:
1x+3x+4x= 128
8x=128
x=128/8
x=16
therefore,
room 1 = 1x
= 1*16=16
room 2 = 3x
=3*16=48
room 3 = 4x
=4*16=64

➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2
To start with, we can use this:
2 (
r^2)
^^ This represents the surface area of the two circles
A cylinder also has a rectangle which is rolled to form the shape
As we know, the formula of a rectangles area is length x width
The width of the rectangle would be equal to the circumference of a circle
circumference of circle = 
The length of the rectangle would be the height of the cylinder
We can use this:

This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.
