Grade: 4-a Lesson: S3-L3 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
The volume of the sphere is 268 cubic feet find its diamter. |
|
2 |
Step |
The given volume of sphere v is |
268 \$meter^3\$ |
3 |
Formula |
The volume of a sphere is three fourth of its square radius |
v = \$3/4 times π times r^3\$ |
4 |
Hint |
Substitute value in the equation, we get |
268 = \$3/4 times π times r^3\$ 268 = \$66/28 times r^3\$ |
5 |
Step |
Move r coefficient to left hand side |
\$r^3\$ = \$268 times 28/66\$ \$r^3\$ = 113.69 r = \$1136 "cubrt" \$ |
6 |
Step |
After simplification, we get |
r = 4.003 |
