Question

Solve the equation x=³ for r.

A. r = √3x (5)
5T
3x
OB.T=√
r
O c. r = √
3x
D. r= √3x - 5

Answer 1

`\sqrt[n3]{(3x)/(5\pi) }` = r

Explanation:

x = 5/3 pi r^3

Solve for r

Multiply each side by 3

3x = 5 pi r^3

Divide each side by 5 pi

3x / ( 5pi) = r^3

Take the cube root of each side

`\sqrt[n3]{(3x)/(5\pi) }` = r
