Suppose that circles r and s have a central angle measuring 80°. additionally, circle r has a radius of 3 ft and the radius of circle s is 6 ft. if the measure of the sector for circle r is 2π ft2, what is the measure of the sector for circle s? a) 8π ft2 b) 9π ft2 c) 10π ft2 d) 12π ft2

b. x + 1

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
