in a circle , the length of an arc intercepted by a central angle is 12mm and the radius of the circle is 8mm. what is the measure, in radians , of the angle . A. 1.5 B. 95 C. 20 D 4.4
Answers
1) we calculate the circumference of this circle. circumference of a circle=2πr data: r=8 mm
circumference=2(8 mm)π=16π mm
2)we calculate the measure, in radians of the angle. We know that: circumference of a circle=2π radians therefore: 16π mm=2π radians.
16 π mm--------------------------2π radians 12 mm----------------------------- x
x=(12 mm * 2π radians) / 16π mm=1.5 radians.
