Points a and b lie on a circle centered at point o.
if oa=5 and length of ab/circumference = 1/4, what is the area of sector aob? use the value pi=3.14.

Choices that should have been accompanied this problem were:
* 19.6 square units
* 39.3 square units
* 7.85 square units

Given:
OA = 5
Length of AB/Circumference = 1/4

Area of sector AOB:

3.14(5²)/4 = 3.14 (25) / 4 = 78.5/4 = 19.625  or 19.6 square units.

Igot 108 hope that’s right !
