consider two circular swimming pools.pool A has a radius of 12 feet,and pool B has a diameter of 7.5 meters.Which pool is has a greater circumference?How much greater?Justify your answers.(1 foot=0.305 meter.)
+36916 Circumference = pi d
A diameter = 24 feet
B diameter = 7.5 m = 7.5 m / .305 m/ft = 25 ft B is larger because diameter is larger....I'll let you calculate the circumferences with the equation in red
