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

Since arc AB is 1/4 of the circumference, the central angle AOB will be 1/4 of a circle, so π/2 in radians. The area of a sector is given by

... A = (1/2)r²·θ

where θ is the central angle in radians and r is the radus.

The area is ...

... A = (1/2)·5²·π/2 = 25π/4

... A ≈ 19.625

The area of the sector is about 19.63 square units.

none cuz there are no "following statements" regarding the question
