Answer:
y = 5
Explanation:
S = 2π r² + 2π r h
let r = 5
let h = height of the cylinder
since the equation is re-written in the form h =
where x and y are constants.
<u>what is the value of y?</u>
<u />
S = (2π r²) + (2π r h) ------ plug in r = 5
S = (2π * 5²) + (2π * 5 * h)
S = (2π * 50) + (10π h)
S = 50π + 10π h
S - 50π = 10π h
S - 50π
h = -------------
10π
S 50π
h = ------ - ---------
10π 10π
S
h = ------ - 5
10π
therefore, the value of y = 5
remember the re-written equation h =
and x and y are constants.
x = 10π as constant
y = 5 as constant
hope it clears your mind.
