A. Cylinder B is 50% smaller than cylinder A

B. Cylinder B is 25% smaller than cylinder A

C. Cylinder B is 150% bigger than cylinder A

D. Cylinder B is 200% bigger than cylinder A

Answer 1

so their difference is 864π - 648π = 216π.

if we take 864π to be the 100%, what is 216π off of it in percentage?
