Question

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

Answer 1

314 units²

Explanation:

Centre of the circle = (0, 0)

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

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

`\text {Radius = }√(6^2 + 8^2)`

`\text {Radius = }√(100)`

`\text {Radius = }10`

Area = π (10)² = 100π = 314 units²
