Question

Solve the equation for r:

V = 5(pi) times r
———————
a^2
• please show work if u understand!!

Answer 1

Explanation:

5πr=V*a²

`r=(Va^2)/(5\pi )`

Answer 2

Explanation:

V = 5*(pi)*r / a^2

V*a^2 = (5*(pi)*r / a^2)*a^2

V*a^2 = 5*(pi)*r

V*a^2 / (5*(pi)) = 5*(pi)*r / (5*(pi))

r = V*a^2 / (5*(pi))
