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

kg/mm³.
To find : Convert this density into kilograms per cubic meter ?
Solution :
We know that,

or 
So, 

Converting
kg/mm³ into kg/m³,
Therefore,
Answer:
3/4
Step-by-step explanation:
1 1/4 * 3/5
Change the mixed number to an improper fraction
1 1/4 = (4*1+1)/4 = 5/4
5/4* 3/5
The 5's cancel
3/4
