Problem |
How can I calculate the volume of a sphere if its radius (r) is 5 centimeters? (pi = 3.14) |
|
2 |
Step |
Given that the radius (r) of the sphere is |
5 cm |
3 |
Formula: |
Volume of the sphere |
\$"V" = (4/3) times π times (r cm)^3\$ |
4 |
Step |
Plug in the value and simplify the equation |
\$"V" = (4/3) times 3.14 times (5 cm)^3\$ \$"V" = 1570/3 (cm)^3\$ \$"V" = 523.33(cm)^3\$ |
5 |
Step |
So, the volume of the sphere with a radius of 5 centimeters is \$523.33(cm)^3\$ |
|

SumUp |
Can you summarize what you’ve understood in the above steps? |
|
7 |
Choice.A |
Correct the volume of a sphere with a 5 cm radius using the right formula |
\$523.33(cm)^3\$ |
8 |
Choice.B |
Incorrect, likely due to a calculation error |
\$503.60(cm)^3\$ |
9 |
Choice.C |
Incorrect. The volume of a sphere is much larger |
\$223.60(cm)^3\$ |
10 |
Choice.D |
Incorrect, not the correct calculated value based on the given radius |
\$323.60(cm)^3\$ |
