area of circle

Question

A circular metallic ring of radius 100cm, is broken to make some equal squares out of it. If the side of a squalre measures 39.25cm. Find the number of squares made.

Answer 1

To find the length of the metal we find the

circumference of the circle... 2πr

 

2π(100) = 628.31853 cm of metal

 

Each square will take 4(39.25 cm) = 157 cm metal per square

 

cm/(cm/square) = squares

628.31853/157 = 4 squares
