Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the volume of cone if radius is 11.2 cm and height 21 cm |
|
2 |
Step |
The given values are |
r = 11.2 cm and h= 21 cm |
3 |
Formula: |
The volume of cone |
\$V = (1/3) times π times r^2 times h\$ |
4 |
Step |
Now substitute the values |
\$V = (1/3) times 3.141 times (11.2)^2 times 21\$ |
5 |
Step |
After simplification |
\$V = (1/3) times 3.141 times 125.44 times 21\$ |
6 |
Step |
After simplification |
\$V = (1/3) times 8274.147\$ |
7 |
Step |
After simplification |
V = 2758.049 cu.cm |
8 |
Step |
The volume of cone is V = 2758.049 cu.cm |
|

10 |
Choice.A |
This is not correct because the value 2758.904 cu.m does not match the correct calculated value |
2758.904 cu.m |
11 |
Choice.B |
This is correct because it has the correct formula and a more accurate numerical value |
2758.049 cu.cm |
12 |
Choice.C |
This is not correct because it is significantly larger than the calculated value and not the closest option |
2765.02 cu.m |
13 |
Choice.D |
This is not correct because the value 2758 cu.m does not match the correct calculated value |
2758 cu.m |
