<h2>Volume of Sphere</h2>

1. What is the radius of the stone sphere?

- To know what is the radius divide is by 2.

  • \large \tt 6 \div 2 = 3

Therefore, the radius of the stone sphere is 3in

2. What is the volume of the stone sphere?

- Using the formula in finding the Volume of Sphere \tt V = \frac{4}{3}\pi r^3 to get the answer. Where the volume of the sphere is \tt\frac{4}{3}\:\:\:\:\pi multiplied by the cube of the radius.

  • \tt V = \frac{4}{3}\pi r^3
  • \tt V = \frac{4}{3}\times 3.14\times 3in^3
  • \tt V = \frac{4}{3}\times 3.14\times 27in
  • \tt V = \frac{4}{3}\times 84.78in
  • \tt V = \frac{339.12in}{3}
  • \tt V = 113.04in^3

Therefore, the volume of the stone sphere is 113.04in³

3. Another stone sphere for the garden has a diameter of 10 inches. What is the volume of the stone sphere? Use 3.14 for <em>π</em>, and round to the nearest hundredth.

- Using the formula in finding the Volume of Sphere \tt V = \frac{4}{3}\pi r^3 to get the answer. Where the volume of the sphere is \tt\frac{4}{3}\:\:\:\:\pi multiplied by the cube of the radius.

  • \tt V = \frac{4}{3}\pi r^3
  • \tt V = \frac{4}{3}\times 3.14\times 5in^3
  • \tt V = \frac{4}{3}\times 3.14\times 125in
  • \tt V = \frac{4}{3}\times 392.5in
  • \tt V = \frac{1570in}{3}
  • \tt V = 523.33in^3

<h3>Explanation</h3>

Therefore, the volume of the stone sphere is 523.33in³
