Answer:
The surface area is 3317.52 inch^2
Step-by-step explanation:
The drum is in the shape of a cylinder, therefore..
Area of the drum
=2πrh+2πr^2
=2*π*12*32+2·π*12^2
= 3317.52 inch^2
1/2^-2 Can be written as 2^2
Therefore , 2×2=4

First you find the area of the rectangle portion, by multiplying 40 by 100 = 4000cm(2)
Next find the area of the triangle by multiplying 30 by 40 then dividing in half.
30*40)/2=600
Now add the two
4600cm(2)
I hope this helps you
Surface Area=2.pi.6.8
Surface Area=96pi
