Question

What is the difference between the total surface area and curved surface area of a cylinder whose radius is equal to $10 cm$ ?

• A. $200 \pi cm ^2$
• B. $300 \pi cm ^2$
• C. $100 \pi cm ^2$
• D. $10 \pi cm ^2$

Answer 1

Answer: (A)

(i) The difference between T.S.A. and C.S.A. of cylinder is $2 \pi{ }^2$.
(ii) The difference of T.S.A. and C.S.A. of a cylinder is $2 \times$ Base area.
