Find the circumferences of the two circles. Circle A has a radius of 21 meters and Circle B has a radius of 28 meters. Use pencil and paper. Is the relationship between the radius of a circle and the distance around the circle the same for all circles? Explain. The circumference of Circle A is nothing meters.

Step-by-step explanation:

Given two circles A and B

        Circumference of Circle A meters

        Circumference of Circle B meters

The larger the radius of a circle, the larger the circumference. We notice that the radius of circle B is larger so its circumference is also larger.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
