Question

I WILL ABSOLUETLY GIVE MEDAL AND FAN YOU IF YOU HELP GIVE THE ANSWER TO MY THIRD LAST QUESTION PLEASE!!!

A cylindrical tank has diameter 3.2 m and length 12.7 m.
What is the surface area of the tank, to 1 decimal place?

Answer 1

do you know what the formula for the surface area of a cylinder?

Answer 2

I Just need the answer im really nervous, im gonna fail, please just answer for medal and fan

Answer 3

hint: \(\large {
\textit{total surface area of a cylinder}=2\pi r(h+r)\quad
\begin{cases}
h\to height\\
r\to radius
\end{cases}

}\)

Answer 4

you 1st need to find the radius of the cylinder

then it depends on you definition of Surface Area

here is Australia its all surfaces...

so the formula is

\[SA = 2\pi r^2 +2 \pi r h \]

which is the area of the 2 circular faces... plus the rectangle with dimensions of

height x circumference.

hope it helps

Answer 5

I don't understand! Just the answer please, I am completely running out of time!

Answer 6

the formula is 2 π r ^2 + 2 π r h
all you have to do is plug in the numbers that you have into the formula.
so it would be 2π(1.6)^2 + 2π (1.6) (12.7)
if you solve it out, it would come out to be about 143.8m^2 to the nearest tenth.
