Answer:
radius of outer circle = 12.5 m
radius of inner circle = (12.5-8.5)m = 4m
circumference of a circle = 2πr
circumference of outer circle
[tex]\\=2*3.14*12.5\\=78.5 m[/tex]
circumference of inner circle
[tex]= 2*3.14*4\\= 25.12m[/tex]
Verified answer
Answer:
Circumference of outer circle is 78.5 mtrs. and inner is 25.12 mtrs.
Step-by-step explanation:
Formula of circumference of a circle is
[tex]2\pi \times r[/tex]
and value of r(radius) in outer circle is 12.5 wheras of inner circle is 12.5-8.5(because the width is 8.5mtrs.)
