Question

TSA of a cylinder with r = 7cm and h= 5 cm is: ​

Answer 1

Given,

Radius of cylinder = 7cm

Height of cylinder = 5 cm

Total surface area of cylinder = 2πr(h+r)cm^2

$2 \times \frac{22}{7} \times 7(5 + 7) {cm}^{2}$

$44(12) {cm}^{2}$

$528 \: {cm}^{2}$

Therefore the total surface area of cylinder is 528 cm^2.

Answer 2

Given-

h = 5cm

r=7cm

Total Surface area of the cylinder = 2πrh+2πr

= 2πr(r+h)

= 2* 22/7* 7 (7+5)

= 2* 22/7* 7* 12

= 2* 22* 12

= 924cm^2
