a$20.25
b$25.50
c$38.25
d$45.75

Answer is D - $45.75

Step-by-step explanation:

(6 x $4.25) + (3 x $6.75) = $45.75

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
