Question

The total surface area of a solid cylinder with radius 7cm and height 13cm is
A) 880cm sq
B) 660cm sq
C) 440cm sq
D) 110cm sq​

Answer 1

Answer:

TSA OF CYLINDER = 880cm sq

Hence, Option A is correct

Step-by-step explanation:

TSA OF CYLINDER = 2πr(r+h)

$= > 2 \times \frac{22}{7 } \times 7(7 + 13) \\ = > 44 \times 20 \\ = > 880 {cm}^{2}$

Hope this helps

Answer 2

Answer:

Step-by-step explanation:

TSA of cylinder=2πrh+2πr2

Height=13cm

Radius=7cm

TSA=2×22/7×7×13+2×22/7×7×2

=44×13+44×2

=572+88

=660sq cm

And=opt b
