What is the Surface Area of the cylinder below?
SA = Acircle + Arectangle
Acircle:
A = pir^2
A = 3.14 x 52
A = 3.14 x 25
A = 78.5cm2
Arectangle:
Circumference = length of rectangle
C = pid
C = 3.14 x 10
C = 31.4cm
Arectangle = L x W
A = 31.4 x 8
A = 251.2cm2
Surface Area = 78.5 + 251.2
Surface Area = 329.7cm2
