CylindersAim: to calculate the volume and surface area of a cylinder
A cylinder is a type of prism.
Area of cross-section x length/height
5cm6cmCalculate the volume of the cylinder:
10cm13cmCalculate the volume of the cylinder:
Surface Area of a Cylinder
Circumference = 2 r or dHeight (h)dhSurface area of curved part of cylinder = d h
Surface area of curved part of cylinder = d hArea of top circle = rArea of bottom circle = r
4cm6cmCalculate the total surface area of the cylinder:Surface Area = ( x 4 x 6) + (2 x x 2) = 24 + 8
= 32
= 100.5 cm (to 1 d.p.)
8cm10cmCalculate the total surface area of the cylinder:Surface Area = ( x 8 x 10) + (2 x x 4) = 80 + 32
= 112
= 351.9 cm (to 1 d.p.)
