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: measure angle 1 is 90°.Measure angle 2 is 35°
Step-by-step explanation:
Measure angle 1 is a right triangle, and that is 90° triangles equal 180 degrees... this means that since measure angle 3 is 55 degrees, and a rhombus is made of 4 equal triangles, then 180°-90°= 90°
90°- 55= 35°
therefore your answers are m<1 90° m<2 35°
