The radius of the sector of the circle with the given area is: B. 3.
<h3>What is the Area of a Sector?</h3>
Area of sector of a circle = ∅/360 × πr².
Given the following:
Area of sector = 9/8 π cm².
∅ = 45 degrees
Plug in the values into the formula
9/8π = 45/360 × πr²
1.125 = 0.125 × r²
1.125/0.125 = r²
9 = r²
r = 3 cm

Answer:
30 degree
Step-by-step explanation:
acb is 60 equilateral triangle
then dac angle is 120 double of centre angle
triangle dac is isoceles so 2 into angle acd=180-120
then acd =30
