Hey there! :D
A= 2πrh+2πr^2 <== surface area for cylinder
A= 2π*82*30+ 2π82^2
A= 15456.63586+42248.13801
A= 57704.77387
So, I think to two decimal places makes it.. 57704.77.
I hope this helps!

Answer:
Step-by-step explanation:
By the geometric mean theorem,
So by the Pythagorean theorem,
If
x+y=-4
y-3x=16 or we cn write as
x+y=-4
-3x+y=16
i multiply the first equation by 3
3x+3y=-12
-3x+ y=16
4y=4
y=1
x+1=-4
x=-5
