Problema Solution
A circle has an area of 25 and is divided into 8 equal parts.What is the perimeter of one portion?
Answer provided by our tutors
Let the radius be r mts
Hence perimeter p=2xpixr= 2x3.14x25=157 mts
One eigth of perimeter p= 157/8=19.625
Therefore perimeter or lenth of boundary of 1/8th of circle=25+25+19.625=69.625 mts
Therefore, answer= 69.625 mts
The unit of the answer will be in whatever units the radius is given.
