Question 457288: A solid cylinder has a radius of 5cm and a height of 12cm. Calculate the total surface area.
Is this how you work it out:
3.142 x 5² = 78.55
78.55 x 12 = 942.6 ? Answer by edjones(7794) (Show Source):
You can put this solution on YOUR website! lateral surface area=pi*2r*h
Top and bottom s.a.=2*pi*r^2
=170pi or 534 cm
