Answer:
The answer is 11.78ft
Step-by-step explanation:
The area for calculating the length of an arc is given as;
Theta/360° × 2πr where;
Theta = central angle = 75°
r is the radius of the circle = 9ft
Substituting the values given into the formula will give;
Length of an arc = 75/360× 2π(9)
= 75/360×18π
= 1350π/360
= 3.75πft
= 11.78ft (to 2 decimal places)
The length of the arc on the circle is 11.78ft
