Answer:
Step-by-step explanation:
Given
- 
← factor denominator
= - 
We require the fractions to have a common denominator.
Multiply numerator/denominator of first fraction by x
= 
-
Subtract terms on numerator leaving the common denominator
= 
=
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
The answer is 5% I’m pretty sure. I just subtracted $40-$30 :)
Here you go :) pls give brainliest
