Which of the following formulas would find the surface area of a right cylinder
where h is the height, ris the radius, and BA is the base area?
Check all that apply.
A. 2pi^2 + 2pi rh
B. BA + 2 pi rh
C. BA + pi r^2
D. Pi r^2 + pi rh
E. 2 pi r^2

Respuesta :

Answer:

A and B

Step-by-step explanation:

Because the surface area is [tex]\pi r^2*2\pi rh[/tex]

BA is the base, so [tex]BA + 2\pi rh[/tex] also works.

Answer: a and b
