How to simplify this 4πr-122.825π —————— =0 r^2

OpenStudy (australia.j.):

4x3.14x122.825x3.14= 23464544.0987013904

OpenStudy (australia.j.):

Do you need to root square it afterwards.

OpenStudy (australia.j.):

if so the answer is 4844.02148

OpenStudy (faiqraees):

122.825π take —————— on the other side and cancel the pi r^2

OpenStudy (anonymous):

I didn't get that. I got r^3=30.70625

OpenStudy (faiqraees):

then multiply r^2 on both sides take cube root and you have the answer

OpenStudy (faiqraees):

got it now?

OpenStudy (anonymous):

So I have 4r=122.825 ————— r^2
