Find 1 round
--------------------------------------------------

1 round of the circle = πD
1 round of the circle = π(2x4)
1 round of the circle =8π

--------------------------------------------------
Find 10 rounds
--------------------------------------------------

10 round of the circle = 8π x 10
10 round of the circle = 80π
10 round of the circle = 251.33 m

251.33m. First find the distance around one circle then times by ten for all the circles.
Circumference of each circle=2x(pi)xr
=2(Pi)x10
=25.13
For ten circles=25.13x10
=251.33

Why is circle 1 similar to circle 2?

DanielleElmas [232]

Answer: The answer is given below.

Step-by-step explanation: The given circles are:

Circle 1: centre (2, 3) and radius 4

Circle 2: centre (2, 3) and radius 12.

The equations of circle 1 and circle 2 are respectively given as :

$(x-2)^2+(y-3)^2=4^2,\\\\(x-2)^2+(y-3)^2=12^2.$
