Question

The sum of the areas of two circular faces of a cylinder is given as:

• A. 2 $\pi$$r^2$
• B. 2 $\pi$$r^3$
• C. $\pi$$r^2$
• D. $\pi$$r^3$

Answer 1

The correct option is A 2 $\pi$$r^2$

Area of circular face of cylinder = $\pi$ $r^2$

Therefore, area of two circular faces = $\pi$ $r^2$ + $\pi$$r^2$ = 2 $\pi$$r^2$
