Question

A cone-shaped container has a height of 6 ft and a diameter of 3 ft. It will be filled with concrete mix that costs $2.00 for each cubic foot.

What will be the total cost to fill the container?

Use 3.14 for π .

Enter your answer in the box.

Answer 1

$28.26

Explanation:

duck

Answer 2

volume of a cone = πr²(h/3)
π=3.14
h=6
r= 1.5

v= (3.14)(1.5)²(6/3)
v= (3.14)(2.25)(2)
v= 14.13 ft³

2 x 14.13 = 28.26

it will cost $28.26 to fill the cone with concrete.
