Question 860551
A cylinder has a surface area of 15 square metres (including

the areas of the ends) and a diameter of 95 cm. What is the

height of the cylinder in metres?
--------------
SA = 2*pi*r^2 + 2pi*r*h
SA = 2*pi*47.5^2 + 2pi*47.5*h = 150000 sq cm
h = (150000 - 2*pi*47.5^2)/(2pi*47.5)
h = 150000/(2pi*47.5) - 47.5
h =~ 455.09 cm
= 4.5509 meters
