38.25 cm²
Step-by-step explanation:
We use the formula for the length of an arc to find the central angle of the sector of the circle.
Then we use the formula for the area of a sector of a circle to find the area.
Length of arc of circle of radius r:

s = arc length
n = measure of the central angle of the sector



Area of sector of circle of radius r:

A = area of sector of circle
n = measure of the central angle of the sector

Answer:
63.5 in
Step-by-step explanation:
y2-y1/x2-x1
28.5-21/2.5-1 = 5
y=mx+b
21=5(1)+b
21-5= 16
b=16
y=mx+b
y=5(9.5) + 16
=63.5
