The correct answer is:
C. The polygon with 8 sides and a concave shape (attached)

Volume of a cylinder of radius r and heigth h is

Here h is 15 cm and r is 6 cm.
Since a coordinate is written as (x,y) then the x-value is 14 and the y-value is 448. Therefore, the answer is 448. Hope I helped!
So J is jelly beans and T is trail mix :)
so J= $3.50
T= $1.50
