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

Well, if you look at the graph, when x = -1, y or f(x) = 4.
and when x = 2, y = 0.
Answer:
Perimeter = 10 cm
Area = 6.25 cm²
Step-by-step explanation:







So to find the Perimeter of the square, we'll use this formula :





Hence, the perimeter would be 10 cm .


We know that the formula of Area to find the square is,

Note : The answer would always be in cm².





Hence, the area of the square would be 6.25 cm².
<em>We are done !</em>
