Using 3.14 for p, find the volume, correct to two decimal places, of a sphere which is 4.5 ft in radius.
To find the volume of a sphere, we use the formula:
V = (4/3) * π * r^3
Given that the radius (r) is 4.5 ft and π is 3.14, we can substitute these values into the formula to find the volume.
V = (4/3) * 3.14 * 4.5^3
First, calculate 4.5^3:
4.5 * 4.5 * 4.5 = 91.125
Now, substitute this result back into the formula:
V = (4/3) * 3.14 * 91.125
Multiply 3.14 by 91.125:
3.14 * 91.125 = 286.0125
Finally, multiply 286.0125 by 4/3:
(4/3) * 286.0125 = 381.350
Therefore, the volume of the sphere is approximately 381.35 cubic feet, correct to two decimal places.
