Line segment AC is tangent to the circle with center O, and CO = 5.
Quantity A |
Quantity B |
Circumference of the circle |
\(10\pi\) |
A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.
we know that C is outside the circumference, therefore, OC is greater than the radius. If we construct an imaginary circle with OC radius we get:
\(r = OC\)
\(C = 2*\pi*5\)
\(C_{OC} = 10*\pi\)
but, given that this radius is greater than BO, the circumference with radius BO MUST be less than \(10\pi\).
Option B
