HELP PLEASE!!!!!Find the radius of a circle if a central angle of 3π/2 intercepts an arc of 26.4 centimeters.0.19 cm3.14 cm5.6 cmFind the measure of a central angle that intercepts an arc of 81.5 cm in a circle whose radius is 16.3 cm.5 rad16 rad65 radFind the arc length intercepted by a central angle of 3π/4 radians in a circle whose radius is 18.4 inches.13.8π15.2π24.5π
Question
Answer:
1: length of arc=(2πr/360)*3π/226.4=r*0.081
therefore,. r=26.4/0.081=325.9cm
this is the answer if the given angle was in degree.
if the angle is in radian then,
26.4=r*3π/2
r=5.6 cm
all the best
