Question

) The diagram shows a quadrant of a circle . If the curved edge is 15 cm long, what is the length of a straight edge?

Answer 1

9.55 cm

Explanation:

A quadrant of a circle is 1/4 of a circle.

Since the curved edge is 15 cm, a full circle would be 60 inches.

60/Pi = diameter

diameter = 60/3.14 = 19.11 cm

diameter/2 = radius

radius = 19.22/2 = 9.55 cm which is the length of a straight edge.
