The circumference of the base of a solid cylinder is 88 cm and its height is 10 cm.
Find
(i) the total surface area,
(ii) the volume
of the cylinder​

Answer 1

Given, 2πr = 88 cm

2 × 22/7 × r = 88

2/7 × r = 4

r = 14 cm

(i) 2πr (r + h)

= 88 (14 + 10)

= 88 × 24

= 2112 cm²

(ii) πr²h

= 22/7 × 14 × 14 × 10

= 22 × 2 × 14 × 10

= 6160 cm³
