QuestionWhich is closest to the volume of the figure shown?
Studdy Solution
STEP 1
What is this asking? We need to find the volume of a cone, given its height and radius. Watch out! Don't confuse the slant height with the actual height of the cone, and don't mix up the formulas for volume and surface area!
STEP 2
1. Recall the formula
2. Plug in the values
3. Calculate the volume
STEP 3
Alright, let's **kick things off**!
The volume of a cone is given by the super cool formula: , where is the **radius** of the circular base and is the **perpendicular height** from the base to the tip-top of the cone.
This formula is like a secret code to unlock the cone's volume!
STEP 4
Now, let's **plug in** our given values.
We have meters and meters.
Notice that we're given the slant height too, but we don't need it for the volume.
That's a sneaky trick to see if you're paying attention!
So, substituting these values into our formula, we get: .
STEP 5
Time to **crunch some numbers**!
First, let's square the radius: .
So now we have .
STEP 6
Now, let's multiply by to get .
So, .
STEP 7
Next, let's multiply by to get approximately .
So, .
STEP 8
Finally, multiplying by (approximately ), we get .
So, our **final volume** is approximately cubic meters.
STEP 9
The closest answer is .
We nailed it!
