plsss..........answer this question very urgent tomorrow exam

Answer 1

answer is 161.07cmsq.
plss mark as brainliest answer

Answer 2

Answer:

Area of sector OAB =X\360°×πr²

=60/360×22/7×21×21

231

here, the triangle ABC is an equilateral triangle, so the area of triangle OAB=√3/4r²=√3/4×21×21

190.73

therefore area of shaded region =231-190.73

=40.27
