Answer:
1739.4 cubic feet
Step-by-step explanation:
Remember that the formula for volume of a cone is V=1/3 πr^2 h, where r=radius and h=height.
First solve for radius: r = d/2, 18.7/2 = 9.35. Plug in:
V = 1/3 π r^2 h
= 1/3 π 9.35^2 * 19
= 553.675π
You can either use 3.14 for pi, or plug it into your calculator.
= 1739.4 cubic feet
Answer:
1,793.7 ft³
Step-by-step explanation:
Volume, V = (1/3) πr²h where,
V = volume of cone
r = radius = (1/2) diameter = 18.7/2 = 9.35 ft
h = height of cone = given as 19 ft
π = 3.142
Substituting the above values into the equation:
V = (1/3) πr²h
= (1/3) (3.142) (9.35)²(19)
= 1,739.6595 ft³ (this is not rounded to the nearest tenth)
= 1,793.7 ft³ (this is rounded to the nearest tenth)
Hope this helps : )
