Question

the area of a minor sector of a circle is 3.85 cm^2 and the measure of the
central angle is 36" Find the radius of the circle​

Answer 1

Answer:

Step-by-step explanation:

Area of sector of a circle = angle/360×πr²

3.85 = 36/360 ×22/7×r²

3.85×10 ×7/22=r²

38.5×7/22=r²

12.25=r²

3.5=r
