Answer:
x = 12
Step-by-step explanation:
The diagram shows an equilateral triangle (because all angles are congruent). All sides in equilateral triangle are congruent, so
Solve the equation
Check this value:
Thus, 
<h2>63.6 cm</h2><h2 />
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area
Answer:
Step-by-step explanation:
A circle is named by its center.
Name of the circle: Circle B
∠DCF = 90° {angle on a semicircle is right angle}
The answer would be 20 degrees.
2*20
3*20
4*20
All triangles must three degrees that equals 180.
