Answer:
4cm
Step-by-step explanation:
well 100 degrees is 1.745 radians
s=r Θ
so r=7/1.745=4 cm
The radius of the circle is 4cm.
The arc of a circle is defined as the part or segment of the circumference of a circle.
Given:
angle = 100 degree
arc length= 7 inches.
We know arc length given by
s=rΘ
Thus, the angle in radian is 1.745 radians
So,
r= s/Θ
r= 7/1.745
r=4 cm
Hence, the radius is 4 cm.
