The circumference of a circle is 14\large \pi inches. What is the area of the circle in square inches? Let's break this question down. Remember the formula for circumference is: \large C=\pi d

If \large C=14\pi, what does d equal? d = inches

If d equals your answer above, what does r equal? r = inches

Remember the formula for area is: \large A=\pi r^2.

So what does area equal? Answer A= inches\large ^2

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.
