Answer:
4.77 cm
Step-by-step explanation:
Hey mate, here is your answer
Let the radius of the circle be 'r'
Then,
2r (72/360) = 6
72/360 can be written as 1/5
2r = 30
r = 15/
r = 15 * 7/22
r = 4.77 cm (approx)

Answer:
RADIUS OF THE CIRCLE IS 4.77cm(approx.)
Step-by-step explanation:
PARAMETERS GIVEN,
ARC LENGTH OF SECTOR = 6cm
CENTRAL ANGLE = 72°
SO,
A.T.Q.,
ARC LENGTH = (Θ/360°)*2πr
6cm = (72/360)*2*(22/7)*r
r = (6*360*7)/(72*2*22)cm
= 4.77cm(approx.)
SO,
RADIUS OF THE CIRCLE IS 4.77cm(approx.)
I HOPE YOU UNDERSTOOD THE QUESTION!!!
