Equilateral triangles always have 3 congruent angles, so the measure of each angle is 60
A basketball is the shape of a sphere.
The volume of a sphere is given by

Given that the diameter of the basketball is 10 in., thus the radius is 10 / 2 = 5 in.
Thus, the volume of the basketball is given by

Therefore, The best approximate of the volume of the basketball is
Answer:
B
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( isolate r by dividing both sides by 2π )
C ÷ 2π = r → B
