You can use the formula of a circumference of a circle, that is
C=2 \pi r
With r = 20 m,
C = 2\pi(20)=40\pi=125.664m
Revoluting it around 10 times, the total distance is
10(125.66m) = 1256.64 m

Let distance the person jogs around the circular garden = x
Circumference of the garden = 2 π r   
       where: π (pi) = 3.14
                   r = radius (20 meters)
Number of times the person jogs around the garden = 10

Equation:

x = 10 (2) (
π) (20 m)
   = 10 (40 m) (π)
   = 400 m (π)
   = 400 m (3.14)
   ≈ 1,256 m

ANSWER: The jogger covered 1,256 meters.
