Question

The volume of the sphere is 500/3π cubic units. What is the value of x?

Answer 1

The volume of a sphere is given by:
4/3 * πr³
From the figure, we can see that x is the radius of the sphere. Therefore, we may substitute x in the formula for volume and equate it to the given volume as follows:
500π/3 = 4/3 * πx³
4x³ = 500
x = 5

The value of x is 5 units

Answer 2

1. The formula of the Volume of a sphere is V(r)=$\frac{4}{3} \pi r^{3}$

2. the radius is x, and the resulting volume is $\frac{500}{3} \pi$ $units^{3}$

3. $\frac{4}{3} \pi x^{3} =\frac{500}{3} \pi$

multiply both sides by 3 and divide them by $\pi$:

$4 x^{3} =500$

$x^{3} = \frac{500}{4}= \frac{250}{2}=125$

$x= \sqrt[3]{125}=5$ (units)
