You need 72.26 inches to frame the mirror
Step-by-step explanation:
Lets revise the rules of a circle
- Its area is A = πr², where r is the length of its radius
- Its circumference is C = 2πr
A circular mirror has a radius of 11.5 inches
We need to frame it
∵ The frame of the mirror is surrounded its circumference
∵ The length of the frame = the circumference of the mirror
∵ C = 2πr
∵ r = 11.5 inches
∴ C = 2π(11.5)
∴ C = 72.26 inches
You need 72.26 inches to frame the mirror
