Answer:
4.90m
Step-by-step explanation:
A sector of a circle of diameter 11 cm is formed from an angle of size 51. Find the length of the arc rounded to two decimal places
Length of an arc = 2πr(θ/360)
(θ) = 51°
r = Diameter/2 = 11/2
= 5.5
Length of an arc = 2 × π × 5.5(51/360)
= 4.89565m
Approximately = 4.90m
