Answer:
The area of the shaded sector is
Step-by-step explanation:
I assume that the problem is
Find the area of the shaded sector of the circle with radius equal to 16 units
step 1
Find the value of x
we know that
-----> by complete circle
The central angle of the shaded sector is 2x
step 2
Find the area of the circle
The area of the circle is equal to
we have
substitute
step 3
Find the area of the shaded sector
we know that
A central angle of 360 degrees subtends an area of circle equal to
so
by proportion
Find the area of the shaded sector by a central angle of 72 degrees
Answer:
I have not been able to answer it sorry
To find unit rate, it's typically done with the equation (y/X). in this case X=minutes and y=laps. so plug the numbers into the equation.(81/27). whatever the answers is, that's your constant of proportionality, or unit rate. multiply your unit rate with the minutes and divide the laps by the unit rate to find the minutes.
minutes=m
laps=l
unit rate=k
m×k=l
l/k=m
