Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Calculate the volume of a cone, if r= 2 cm and h= 7 cm. (use π = 22/7) |
|
2 |
Step |
Given that π (pi) is radius is and height is |
\$22/7\$ 2 cm 7 cm |
3 |
Formula: |
Volume of a cone |
\$"V" = (1/3) \times π \times (r)^2 \times h\$ |
4 |
Step |
Substitute the values into the formula |
\$"V" = (1/3) \times 22/7 \times (2 cm)^2 \times 7 cm\$ \$"V" = (1/3) \times 22/\cancel7^1 \times 4 \times \cancel7^1cm\$ |
5 |
Step |
Simplifying this expression |
\$"V" = 1/3 \times 22 \times 4\$ \$"V" = 88/3 = 29.33(cm)^3\$ |
6 |
Step |
So, the volume of the cone with a radius of 2 cm and a height of 7 cm is \$29.33(cm)^3\$. |

SumUp |
Can you summarize what you’ve understood in the above steps? |
|
8 |
Choice.A |
This is the correct answer. It correctly follows the formula for the volume of a cone and provides an accurate calculation |
\$29.33(cm)^3\$ |
9 |
Choice.B |
Volume is measured in cubic units (cm^3), not in square units (cm^2) . This option is incorrect |
\$62(cm)^4\$ |
10 |
Choice.C |
Volume is not measured in the fifth power (cm^5). This option is incorrect |
\$60(cm)^5\$ |
11 |
Choice.D |
Volume is not measured in the sixth power (cm⁶). This option is incorrect |
\$65(cm)^6\$ |
12 |
