A circle is centered at the origin and contains the point (-6, -8). What is the area of this circle?​
gogolik [260]

Answer:

314 units²

Step-by-step explanation:

Centre of the circle = (0, 0)

Another point on the circle = (-6, -8)

\text {Radius = }\sqrt{(0 - (-6))^2 + (0- (-8))^2}

\text {Radius = }\sqrt{6^2 + 8^2}

\text {Radius = }\sqrt{100}

\text {Radius = }10

Area = π (10)² = 100π = 314 units²
