Question 425787: how did we come up with the formula for surface area of a cylinder. Found 2 solutions by richard1234, Heaven Creater:Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! The surface of a cylinder is composed of two parts: the areas of the bases and the lateral surface area. If the base is assumed to be a circle, the area of one base is just so the area of both these bases is . The lateral surface area is essentially a rectangle with height h and base equal to the circumference of the circle. The circumference is , so the lateral surface area is . Add this with to obtain the surface area.
You can put this solution on YOUR website! Wait,are you asking whats the formula for a cylinder?? If so here it is:
pi:(3.14;22/7;or pi symbol.your choice)so anyways its ( the 2 BASES+CIRCUMFERENCE x HEIGHT)so the real translation of that formula is this formula :
example: A cylinders radius is 4cm and its height is 10cm.
Formula:
Solution: =352cm <-----Answer;just plug ALL THAT in your calculator and remember,USE 3.14 or 22/7,or the Pi symbol for Pi.!
Hope this helped!
