Question

A circular labyrinth has a circumference of 75 feet what is the distance from the outside edge of the labyrinth in to it center use 3.14 for pie round your answer to the nearest foot

Answer 1

The distance from the outside edge of a circle to its centre is given by its radius. The circumference of a circle is given by 2πr, thus if we know that this is equal to 75 feet and using π = 3.14, we get:

75 = 2*3.14*r
r = 11.942
Thus r = 12 ft (to the nearest foot)
