Answer:
y=2
Step-by-step explanation:
all horizontal lines are y=(the y intercept/line height)
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:
you would have to multiply times 4
Step-by-step explanation:
10^3= 1000
Therefore 1000x1579
= 1579000
