Answer:
The volume of a cone is 
.
Step-by-step explanation:
We have,
Diameter of a cone is 7.5 ft
Radius of a cone is 3.75 ft
Height of the cone is 4.25 ft
It is required to find the volume of the cone. The formula of the volume of cone is given by :
So, the volume of a cone is .
That's the simplest form of 15/35. You can use
3/7 to get other equivalent fractions by multiplying the numerator and denominator by the same number. Other examples are
9/21, 6/14, and 12/28.
Hope this helps!
