A box of a dozen fruit tarts costs $15. How much money does 1 fruit tart cost?

1 dozen = 12 so 15/12 is 1.25

which means 1 fruit tart is $1.25

.

step-by-step explanation:

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 !
