Rewrite the formula to find the radius of a sphere. The volume (V) of a sphere is given by the formula . The sphere’s radius (r) is .

A.(3V/pi)1/3
B.4V/3pi)1/3
C.(3pi/4V)1/3

Respuesta :

V = (4/3) pi r^3

r^3 = V / (4pi/3)

r^3 = 3V /  4pi

r  = (3V/4Pi)^(1/3)

Answer:

Option C is correct

[tex]\sqrt[3]{\frac{3V}{4 \pi}}[/tex] units

Step-by-step explanation:

Volume of a sphere(V) is given by:

[tex]V = \frac{4}{3} \pi r^3[/tex]          .....[1]

where,

[tex]3V = 4 \pi r^3[/tex]r is the radius of the sphere.

We have to find the radius r:

Multiply both sides by 3 both sides in [1]  we have;

[tex]3V = 4 \pi r^3[/tex]

Divide both sides by [tex]4\pi[/tex] we have;

[tex]\frac{3V}{4 \pi} = r^3[/tex]

Taking cube root both sides we have;

[tex]\sqrt[3]{\frac{3V}{4 \pi}} = r[/tex]

or

[tex]r = \sqrt[3]{\frac{3V}{4 \pi}}[/tex] units

Therefore, the radius of the sphere is, [tex]\sqrt[3]{\frac{3V}{4 \pi}}[/tex] units
