16 ≤ 12
Not true
2. 12 ÷ (12) > 12
1 > 12
Not true
3. 12 - (12) ≥ 4
0 ≥ 4
Not true
4. 12(12) < 200
144 < 200
True

We know that formula for volume of cone is 1/3 πr² h where r is radius and h is height.

Now we know that r is 2 and volume is 29 so we can set up equation like this:

29 = 1/3 π (2)² h

Now we need to solve for h:

29 = 4/3 π h

Divide both sides by 4/3 π:

29 / (4/3 π) = h

87 / (4π) = h

Use calculator here

h ≈ 6.92675159

Round to nearest hundredth:

h ≈ 6.93

Final 6.93
