First we must make each fraction improper. To do so, we must multiply the whole number by the denominator and add the product to the numerator. That would give us 63/8 - 13/4. Now we have to make the denominators the same. To do so, we will just multiply the numerator and denominator of 13/4 times 2 to get 26/8. 63/8 - 26/8 = 37/8. Simplified it is 4  5/8.

What is the volume of a cone-shaped popcorn cup that is 8 inches tall and 6 inches across at the base?
Alina [70]

The volume of cone shaped popcorn cup is 75.36 cubic inches.

According to the given question.

The height of the popcorn cup = 8inches

And the diameter of the cup = 6 inches

⇒ Radius of the popcorn cup = 6/2 = 3 inches

As we know that, the volume of cone is calculated by the formula

volume of cone = (πr^2h)/3

Therefore, the volume of cone shaped popcorn cup

= 3.14((3)^2)(8)/3

= 3.14(3)(8)

= 75.36 cubic inches

Hence, the volume of cone shaped popcorn cup is 75.36 cubic inches.
