Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
The volume of a cone is \$43π cm^3\$. Its diameter is 6cm.Find its height. |
|
2 |
Step |
The given values are |
V = 43π , d = 6 |
3 |
Formula: |
The volume of cone is |
\$ V=1/3 π r^2 h\$ |
4 |
Hint |
\$r = d/2\$ |
\$r = 6/2\$ |
5 |
Step |
Now substitute the values |
\$43π = 1/3 times π times (3)^2 times h\$ |
6 |
Step |
After simplification |
\$43π = 3π times h\$ |
7 |
Step |
After simplification |
\$h = 43π /3π\$ |
8 |
Step |
After simplification |
h = 14.33 cm |
9 |
Step |
The height of a cone is 14.33 cm |

Sumup |
Can you summarize what you’ve understood in the above steps? |
|
11 |
Choice.A |
This is incorrect because the measurements have different units. The units should be used for volume, not height |
\$14.32 m^3\$ |
12 |
Choice.B |
This is wrong because the measurements share the same units, but the error lies in the calculations |
9.426 m |
13 |
Choice.C |
This answer is right because the measurements use the same units, ensuring the calculation is done accurately and precisely |
14.33 m |
14 |
Choice.D |
This is incorrect because the measurements have different units. The units should be used for volume, not height |
\$9.426 m^3\$ |
