Answer:
Circumference = 750 m / 3
Circumference 250 m
Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters
Solving for the diameter
250 m = pi * D
D = 250 m / pi
D = 79.58 m is the diameter of the circular field
Solving for the radius
r = 1/2 D where r is the radius of the circular field
r = 39.59 m is the radius of the circular field
Answer:
d = 79.62 m
r = 39.81 m
Step-by-step explanation:
750/3 = 250 m (circumference of the circle)
diameter = circumference/pi
= 250 m/3.14
diameter = 79.62 m
radius = diameter / 2
= 79.62 m / 2
radius = 39.81 m
