Points a and b lie on a circle centered at point o. if oa = 5 and length of abowncircumference=14, what is the area of sector aob? use the value π = 3.14, and choose the closest answer.

This question can simply be answered directly. To solve this, we should recall that the formula of a circle is:

Area of circle = π r^2                       where r is the radius of the circle

Now we are given that segment OA is equivalent to 5 units. Segment OA is also the diameter of that circle therefore d = 5.

Now let us convert the formula knowing that radius is one half the diameter:

r = d / 2

Area of circle = π (d / 2)^2

Area of circle = π d^2 / 4

Substituting:

Area of circle = π (5)^2 / 4

Area of circle = 3.14 * 25 / 4

Area of circle = 19.625 = 19.6 square units

The answer would be 19.6 for plato Users
