a = 2πr2 + 2πrh
∴da/dr = 4πr + 2π(h + r dh/dr)
Total surface area of the cylinder in square units: (2*pi*144)+(24*pi*15) = 648*pi
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...

Given: a = 2πr2 + 2πrh h = 113/r2 ∴ a = 2πr2 + 2πr(113/r2) ∴ a = 2πr2 + 226π / r ∴ da/dr = 4πr + 226π ln r
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
This cylinder's surface area is 980.21 units2
The surface area is 747.7cm2
no
The surface area of this cylinder is 2,111.15 square feet.
The cylinder's surface area is 4,241.15 square inches.
if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder
Complete surface area = (2*pi*72)+(14*pi*15) = 308*pi square cm
