Question

Find h if A = 80π and r = 5

Answer 1

is the question correct?

Answer 2

* The formula for the surface area of a cylinder is A = 2πr(r + h).
Find h if A = 80π and r = 5

Answer 3

so sorry 3

Answer 4

if u know the formula then u can solve this one and i nm noticing u test people

Answer 5

\[A = 2 \pi r ( r+ h)\]
\[80 \pi = 2 \pi (5)(5+h)\]
\[8 = 5 + h\]
h = 8 - 5
h = 3

Answer 6

Can you do this problem step by step with me to explain it?

Answer 7

\[A = 2 \pi r ( r+ h)\]
\[80 \pi = 2 \pi (5)(5+h)\]
\[80 \pi = 10 \pi (5+h)\]
Divide 10 pi on both sides.
\[\frac{80 \pi}{10 \pi} = (5+h)\]
\[8 = 5 + h\]
h = 8 - 5
h = 3
