Answer:

Step-by-step explanation:
Step 1: Identity the radius.
Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,
OC=OE.
Step 2: Consider the rectangle.
All diagonals in a rectangle are congruent so this means
DB= OC ( OC is also a diagonal).
Thus, OC= 10 units.
Step 3: Analyze
So this means OE is also 10 units as well.
Since we know the length of the radius, Use the area of circle,


So the area of a circle is 100 pi.
Answer:
x = -2
Step-by-step explanation:
2(4x+8)
= 8x+16
8x+16 = 0
-16 -16
8x = -16 (do -16÷8 & get)
x = -2
Answer:
Step-by-step explanation:
Answer 2x-3y+3=0
The problem focuses on the simplification of the function
y-3=2/3(x-2)
Y-3=2/3-2
3y-9=2x-6
2x-3y+3=0
