Given:
Radius = 7r in
Let's find the volume of the sphere.
To find the volume of the sphere, apply the formula:
![V=(4)/(3)\pi r^3](https://img.qammunity.org/2023/formulas/mathematics/high-school/zraet4fw93vx9gjz3iextthjo546ibcpwc.png)
Where:
r is the radius = 7 in
Thus, we have:
![\begin{gathered} V=(4)/(3)*\pi *7^3 \\ \\ V=(4)/(3)*\pi *343 \\ \\ V=1436.7\approx1437\text{ in}^3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/4lfbu50jnwnneht2shfw8xsdavm2mjcjq0.png)
Therefore, the volume of the given sphere rounded to the nearest whole number is 1437 cubic inches.
ANSWER:
1437 in³
