Answer: 7/8
Cos2x has 3 formulas, Sinx is given in the question, we should use the formula with sinus. I guess that's the solution.

Answer:
Volume of sphere = 1.3 * 10^-7 cubic meters.
Step-by-step explanation:
Given the following data;
Diameter, D = 6.4 mm to meters = 6.4/1000 = 0.0064 meters.
But, Radius = diameter/2
Radius = 0.0064/2 = 0.0032 meters.
π = 3.14
To determine the volume of sphere, we would use the formula;
Substituting into the equation, we have;
Volume of sphere = 1.371886933 * 10^-7 cubic meters.
To the nearest tenth;
Volume of sphere = 1.3 * 10^-7 cubic meters.
