Find the volume of the figure. figure is in the website below. For calculations involving π, give both the exact value and an approximation to the nearest hundredth of a unit. Let
d = 8 and h = 18.

the question was to get the exact value in ft^3 and approximate value in ft^3
you probably know that the volume of a cone is
1/3 π r^2 h
They gave you the diameter, so
v = 1/3 π (d/2)^2 h = 1/12 πd^2h
Now just plug in your values for d and h
To find the volume of the figure, we need to determine which shape it represents.
From the given dimensions, d = 8 and h = 18, it can be inferred that the figure is a cone.
The formula for the volume of a cone is given by:
V = (π * r^2 * h) / 3
To calculate the volume, we need to find the radius of the cone.
Given that d = 8, we can find the radius (r) by dividing d by 2:
r = d / 2 = 8 / 2 = 4
Now, we can substitute the values into the formula to find the volume:
V = (π * 4^2 * 18) / 3
Simplifying the equation:
V = (π * 16 * 18) / 3
V = (288π) / 3
For the exact value, the volume is given as (288π) / 3.
For the approximation to the nearest hundredth of a unit, we can use the approximation π = 3.14:
V ≈ (288 * 3.14) / 3
V ≈ 902.88 / 3
V ≈ 300.96 (rounded to the nearest hundredth)
Therefore, the volume of the given figure is approximately 300.96 units^3.
To find the volume of the given figure, we need to determine the shape of the figure. Unfortunately, as an AI text-based model, I am unable to access or view images or websites. However, I can still explain how you can find the volume based on the information you provide.
If the figure is a cone, cylinder, or any other regular shape, you can use the appropriate formula to calculate the volume.
For example, if the figure is a cylinder, the volume formula is V = πr^2h, where r is the radius of the base and h is the height.
If the figure is a cone, the volume formula is V = (1/3)πr^2h, where r is the radius of the base and h is the height.
Without further information about the specific shape of the figure or its dimensions, it is not possible to provide an accurate calculation of the volume.
If you can provide more details or describe the figure or dimensions, I would be happy to help you further.
