How do you find the area of all the surfaces of a cylinder given the measures of its height and the diameter of one of its bases

Report as

As I read the question, it seems that it is asking for the 3 possible areas a cylinder has: the one for the base; the one for the top (which is the same as the base); and the one from the side as if it were cut longitudinally and opened as a rectangle. The area of the base (and top) is (D/2)^2 x Pi. The area of the side is the circumference of the base x the High = (D x Pi) x H. If indeed you need the sum of all of this, then just add them together.

Thank you so much my daughter is 10 years old and in a gifted middle school I really needed help with this question....Guess I'm not smarter than a 5th grader.....Lol

Glad to help. Just remember to give a thumbs up when you like an answer. ;-)

Area of all surfaces of cylinder = 2 x Base area + Lateral area
Base area = area of circle = pi.(r)^2
Lateral area = 2.pi.r.h
