[tex] \bf \huge \: 11 \: inches.[/tex]

Step-by-step explanation:

Given :

  • The circumference of a circle is 7π in.

to find :

  • Find its radius, in inches.

formula used :

  • r = c/2

where,

  • r = radius
  • c = circumference

explanation :

⟼ r = c/2

⟼ r = 7×22÷7/2 in

⟼ r = 22/2 in

⟼ r = 11 in.

  • Hence, radius is 11 inches.
