Question

The diameter of the base of right circular cylinder is 2r and its height is h. What is the total surface area of cylinder?

Answer 1

Answer:

6.28(r^2+rh)

Step-by-step explanation:

Since the formula for the surface area of the cylinder is 2πr(r+h).

Answer 2

Answer: 2πr(h+r)

Step-by-step explanation:

$\huge\underline\purple{\sf Given :-}$

• Diameter of the base of right circular cylinder is 2r
• Height of cylinder is h

To find: Total surface area of the cylinder

Solution:

→Diameter= 2r

Therefore, Radius will be 2r/2 = r

→ Given Height is 'h'

† T.S.A of cylinder = 2πr(h+r)

Therefore, Total surface area of cylinder will be 2πr(h+r)
