Question

An arc on a circle measures 85°. The measure of the central angle, in radians, is within which range? 0 to StartFraction pi Over 2 EndFraction radians StartFraction pi Over 2 EndFraction to π radians π to StartFraction 3 pi Over 2 EndFraction radians StartFraction 3 pi Over 2 EndFraction to π radians

Answer 1

Answer: A. 0 to pi/2 radians

Explanation:

Answer 2

0 to StartFraction pi Over 2

Explanation:

we know that

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

so

The central angle in degrees is within the range
`(0,90^o)`

Convert to radians

Remember that

`(\pi)/(2)\ radians=90^o`

therefore

the range in radians is
`(0,(\pi)/(2))`

0 to StartFraction pi Over 2
