Answer:
314 cm²
Step-by-step explanation:
It's not the point O, but the circle O, a point has no area.
The area of a circle is given by the formula A = π r²
We don't have r (radius), but we have the diameter, which is double the radius. So, r = d / 2 = 20 cm / 2 = 10 cm
Now, we can plug r directly into the equation:
A = π r² = π 10² = 100π = 314 cm²
Answer:
Only odd numbers are existed.
The answer is H to your question
D=√(x2-x1)² + (y2-y1)²
D=√(-6 3/4-8 1/2)² + (7 1/2-12)²
D=√(-15 1/4)² + (-4 1/2)²
D=√3721/16 + 81/4
D=√4069/16
D=64/4
D=16
