+267 A sector of a circle is shown below. The sector has an area of $60 \pi.$ What is the radius of the circle?
+15134 Where is the circle sector shown??
What is the radius of the circle?
\(A_{sector}=\dfrac{\pi r^2\alpha}{360°}\\ A_{sector}=\dfrac{60}{\pi}\\ r_{sector}=\sqrt{\dfrac{60\cdot 360°}{\pi \alpha}\cdot \dfrac{2\pi}{360°}}\\ \color{blue}r_{sector}=\sqrt{\dfrac{120}{\alpha }}\)
