Remember the equation for the area of a circle.
A = pi r^(2)
To find 'r' algebrucally rearrange
r^(2) = A/pi
Do not forget to Square Root BOTH sides
r = sqrt(A/pi)
r = sqrt(345 / 3.141592....) )
r = sqrt(109.8169107....)
r = 10.47935641... cm ~ 10.5 cm

How do you find the radius of an inscribed circle of a square given the area of the circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
What is the area of a circle with a radius of 4.4?
To find the area of a circle based on its radius, multiply its radius squared by pi. Don't forget to square the radius before multiplying by pi, based on rules of BODMAS where you find powers of numbers before you multiply them.In this instance, (4.4 x 4.4) = 19.36. Multiplying this by pi gives us, accurate to two decimal places, 60.82. Don't forget to include the appropriate measurement. If the original measurement of the radius of the circle was in centimetres, then the area should be expressed in square centimetres. If the original measurement of the radius was in inches, then the area should be expressed in square inches.
