Question

how do you go from cicles area to the radius

Answer 1

Do you have a problem to solve that could be used to illustrate how to do this?

Answer 2

50.26 is the area what is the radius

Answer 3

since
\[A=\pi r^2\] you can solve for r and get
\[r=\sqrt{\frac{A}{\pi}}\]

Answer 4

Sadly there is no picture

Answer 5

i need a simpler way to understand this like an example and not just the formula

Answer 6

then a specific question would probably work best

Answer 7

if the area is 50.26 what is the radius

Answer 8

50.26 is the area

The area of a circle is pi r^2 where r is the radius and pi is the irrational number beginning 3.14.

Area of a circle is pi r^2

50.26 = 3.14 * r^2

50.26/3.14 = r^2

16.006 = r ^2

4.00 = r (answer is approximate due to rounding for pi)

Answer 9

thank you
