The formula for the volume of a sphere is V = 4/3πr³, where r is the radius.
To find the radius of the volleyball, we can use the formula for the circumference of a sphere: C = 2πr.
Rearranging this formula, we get r = C/2π.
Substituting in the given circumference of 72.2cm, we get:
r = 72.2/2π ≈ 11.5 cm
Now we can use this radius to find the volume:
V = 4/3π(11.5)³ ≈ 6516.1 cm³
Rounding to the nearest tenth, we get the approximate volume of the volleyball as 6516.1 cm³.
3.
The circumference of the volleyball shown is approximately 72.2 centimeters. What is the approximate volume of the volleyball? Use 3.14 for π.
The answer is rounded to the nearest tenth.
