Question 1021765: Find the surface area of each cylinder given the base radius and height of the cylinder. Round to the nearest square unit
R= 7 ft
H= 25ft

( if the capital D does not work use a lower case d )
P.s sorry messed up the first time :P

You can put this solution on YOUR website!
Surface area of a cylinder = 2%2Api%2AR%5E2+%2B+2pi%2AR%2AH
given:
R=7ft
H=25ft
the area is:
A=2%2Api%2AR%5E2+%2B+2pi%2AR%2AH
A=2%2Api%2A%287ft%29%5E2+%2B+2%2Api%2A7ft%2A25ft
A=2%2Api%2A49ft%5E2+%2B+2%2Api%2A175ft%5E2
A=pi%2A98ft%5E2+%2B+pi%2A350ft%5E2
A=%2898ft%5E2+%2B+350ft%5E2%29pi
A=448ft%5E2%2Api.....pi=3.14
A=1406.72ft%5E2
A=1407ft%5E2
