If a sphere has a diameter of 4 inches, what is the volume? Use 3.14 for
pi*D^3/6
To find the volume of a sphere, you can use the formula:
V = (4/3) * π * r^3
Given that the diameter of the sphere is 4 inches, we know that the radius (r) is half the diameter. So, the radius is 4 inches ÷ 2 = 2 inches.
Now we can substitute the value of the radius into the formula:
V = (4/3) * 3.14 * 2^3
First, calculate 2^3:
2^3 = 2 * 2 * 2 = 8
Now, substitute the value back into the formula:
V = (4/3) * 3.14 * 8
Simplify the equation:
V = 33.49 cubic inches (rounded to two decimal places).
Therefore, the volume of the sphere is approximately 33.49 cubic inches.
