Answer:
set the equations to ____ = 360/90
Step-by-step explanation:
for example, a, the equation is 2a + 90 = 360
-90 -90
---------------------
2a = 270
/2 /2
a=135
Answer:
37.03 sq. mm.
Step-by-step explanation:
A sector is "part" of a circle. The formula for area of a sector (in radians) is:
Area of sector =
Where
r is the radius (half of diameter)
is the central angle of the sector
In this problem, the diameter is given as 20.6, so radius would be:
Radius (r) = 20.6/2 = 10.3
The central angle is given as radians
Now, we substitute and find the value for the area:
Thus,
Area of sector = 37.03 sq. mm.
