# The diameter of a cylinder is 14 cm and its height is 15 cm. Calculate the total surface area and volume of the cylinder.

Diameter of cylinder = d = 14 cm

radius of cylinder = r = = = 7 cm

Height of cylinder = h = 15 cm

Total surface area will be the sum of curved surface area and the area of two circles flat surfaces

Total surface area of cylinder = 2πrh + 2πr2

= 2 × × 7 × 15 + 2 × × 72

= 30 × 22 + 2 × 22 × 7

= 660 + 308

= 968 cm2

Volume of cylinder = πr2h

= × 72 × 15

= 22 × 7 × 15

= 22 × 105

= 2310 cm3

Therefore, total surface area of cylinder is 968 cm2 and volume is 2310 cm3
