Given:
In the given circle, ∠ADB = 270° and length of ADB = 61.26 m
To find the radius of the circle.
Formula
The formula to determine the radius is given by
[tex]arc \ length =(\frac{\theta}{360})2 \pi r[/tex]
Substituting arc length = 61.26, [tex]\theta= 270[/tex], we get;
[tex]61.26 =(\frac{270}{360})2 (3.14) r[/tex]
[tex]61.26 =4.71 r[/tex]
[tex]13=r[/tex]
Thus, the radius is 13 m
