Question 2 Mensuration Exercise 18.4

Find the total surface area of a solid cylinder of radius 5 cm and height 10 cm. Leave your answer in terms of n.

Answer:

Given,

Radius of a solid cylinder (r) = 5 cm

Height (h) = 10 cm

Hence,

Total surface area = 2πrh + 2πr2

= 2rπ(h + r)

= 2π × 5(10 + 5)

= π × 10 × 15

= 150π cm2
