Acircular mat has a radius of 53 centimeters. lily wants to sew a decorative braid around half of the mat. how many centimeters of braid does she need

To find the perimeter of a circle the equation is P = 2 * Pi * R. Pi = 3.142 and R = radius. now if you know the diameter The equation is P = Pi * D.

Step-by-step explanation:

So we plug 53 in to

P = 2 * 3.142 * R

And come out with

P = 2 * 3.142 * 53

P = 333.052

And if Lily wants to sew half of it take 333.052/2

The answer is Lily will need 167 cm of braid

I hope this helped if some a thanks and a 5 stars would be appreciated.

Have a good rest of your day.
