Q. The questions below are posed in order to help you think about how to find the number of degrees in 125π radians.What fraction of a semicircle is an angle that measures 125π radians? Express your answer as a fraction in simplest terms.
Total Radians in Semicircle: To find the fraction of a semicircle that an angle of (5π)/(12) radians represents, we need to know the total radians in a semicircle. A semicircle is half of a circle, and a full circle is 2π radians. Therefore, a semicircle is π radians.
Calculate Fraction: Now, we divide the angle in question, (5π)/(12) radians, by the total radians in a semicircle, which is π radians. This will give us the fraction of the semicircle that the angle represents.Calculation: (5π)/(12)÷π=5/12
Check Simplified Form: We should check that the fraction is in its simplest form. Since 5 and 12 have no common factors other than 1, the fraction 125 is already in simplest form.
