Johnny ran 20 laps around a circular field. If he covered a distance of 3265.6 metres, what is the radius of the circular field?

60?

Step-by-step explanation:

2πr = 163.28

20(2πr) = 3265.6

r ≈ 60.927382

25.99 metres

Step-by-step explanation:

2πr is the circumference equation for the distance of one lap. Multiply that by 20 to get the distance of the laps in total. Then, simplify with r (radius) as the variable to solve for.

20(2πr) = 3265.6

2πr = 163.28

r ≈ 25.986819108

astronomers is your final answer! : )

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
