Solve both the formula for the circumference of a circle and the formula for the area of a circle for π. Use these equations to write a proportion comparing the circumference and the area of a circle.

after simplifying it i got: -36.25 as my answer. hope that !

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
