Question

how to find radius of circle whose area is 314 22by 7​

Answer 1

Answer:

10

Step-by-step explanation:

Since the formula for finding the area of a circle is A = πr^2we could plug in what we have

314 =3.14 r^2

Then divide 314 by 3.14 to find the missing variable.

314/3.14= 100

100 is the radius squared so we have to find the perfect square of 100

√100= 10
