Question

Find the total surface area of right circular cylinder
whose height is 14 cm and radius of outer end is double of
radius of inner end where it is 7 cm.​

Answer 1

Answer:

1232 cm^2

Step-by-step explanation:

t.s.a of cylinder = 2πr(r+h)

r = 2 x 7 = 14

= 2×π×14×14

= 2× 22/7 ×14×14

= 2×22×14×2

=1232 cm^2
