Question

There perimetre of quarter circle is 14.28mm. What is the quarter circle radius.

Answer 1

Answer:

9.087 m

Step-by-step explanation:

Perimeter of circle = 2 * pie * r

Perimeter of circle = 4 * quarter circle perimeter

so, 2 * pie * r = 4 * 14.28

2 * 22/7 * r = 4 * 14.28

r = 4 * 14.28 * 7 /2/ 22

= 9.087
