PLEASE HELP
Circle A has circumference 2 2/3 m. Circle B has a diameter that is 1 1/2 times as long as Circle A’s diameter. What is the circumference of Circle B?

Answer:

8 meters.

Step-by-step explanation:

Formula:    Circumference  C = 2*π*r

Circle A circumference:    a = 2 and 2/3 m = 2*π*r

circle B has diameter = 1 and 1/2 *  2r =  (3/2)* 2r = 3r

so

Circumference of circle B  = 2*π*(3r)

here r =   (8/3)/(2*π)=  4/(3*π)

B  = 2*π*(3*  (4/(3*π)) )  = 2*π* (4/π)  = 8 meters.
