Consider the circle with a 4 centimeter radius. if the length of major arc rt is
64/9π, what is the measure of ∠rst?
a.20
b.25
c.30
d.40

Option D is correct.i.e., ∠ RST = 40°

Step-by-step explanation:

Given: Radius of circle, r = 4 cm

           Center of circle is S and Length of Major ARC RT =

To find: ∠ RST

Figure is attached

Let be the ∠ RST.

we use the formula of Length of Arc,

We use this formula to find the angle made by arc RT at centre S,

Therefore, Option D is correct.i.e., ∠ RST = 40°
