The volume of a cone is such that $V= \frac{1}{3} \pi r^2h$ , where r is the radius and h is the height.

Recall that the diameter is twice the radius. So given that the diameter is 8 ft, the radius must be 4 ft. The height is given as 5 ft.

Plugging into the formula, you have $V= \frac{1}{3}(3.14)(4)^2(5) = 83.73 \ ft^3$

Is 1.875 a terminating decimal

vampirchik [111]

Answer:

Because they are fractions, any rational number can also be expressed in decimal form. Any rational number can be represented as either: a terminating decimal: 158=1.875 15 8 = 1.875 , or. a repeating decimal: 411=0.36363636⋯=0.

Step-by-step explanation:
