Answer: 267.947 (or 267.95) inches^3
Step-by-step explanation:
The formula for the volume of a sphere is .
To find your radius (r), divide the diameter of 8 inches by 2. <em>The radius is 4 inches.</em>
Plug in your numbers to the volume equation to get . The first step is to cube 4 (4*4*4) to get <em>64</em>. Now your equation is
.
Multiply 3.14 and 64 to get <em>200.96</em>. The equation is now or
.
Multiply the numerators (4 * 200.96) and denominators (1 * 3) to get a final equation of .
Finally, divide 803.84 by 3 to get the final answer of 267.947 in^3.
