Acone shaped funnel has 314 cubic inches of water. if the height of the funnel is 12 inches, what is the radius of the tunnel?

The correct answer is that the funnel has 5 inches of radius.

Step-by-step explanation:

To calculate the volume of a cone, you need to multiply the base area, in this case the area of a circle: π * r², by its height and then by 1/3:

Volume of a cone = (1/3) * π * r² * h

Now, let's replace the values given in the question for finding out the value of the radius.

314 = (1/3) * 3,14 * r² * 12

314 = 4 * 3.14 * r² (after multiplying 12 x 1/3 on the right side)

100 = 4 * r² (after dividing by 3,14 at both sides of the equation)

25 =  r² (after dividing by 4 at both sides of the equation)

5 = r (after calculating the √ of 25)

A cone shaped funnel with a volume of 314 inches of water, a height of 12 inches has a radius of 5 inches.
