Hi guys!
(Please help me if you have time)​

528 m

Step-by-step explanation:

circumference = 2(Pi)(radius) = (2)(22/7)(28) = 176 m

176 x 3 = 528 m

528m

Step-by-step explanation:

given the radius 28m, we can find the circumference of the circle using the formula C=2pi×r

substitute the given into the formula we get C=2(22÷7)×28, since pi is equals to 22/7.

C=176m

Now we multiply the result by 3 since it says that it took three rounds, we have 176m×3= 528m

Hope this helps you...
