Calculate 83356

The distance of the chord from the center is 6 cm. The central angle is 60°. Calculate the area of the circular segment.

Correct answer:

S =  4.3481 cm2

Step-by-step explanation:

h=6 cm α=60° rad=60° 180π =60° 1803.1415926 =1.0472=π/3  β=α/2=1.0472/20.5236 rad  cos β = h:r  r=h/cosβ=6/cos0.5236=4 3 cm6.9282 cm  S=2r2 (αsinα)=26.92822 (1.0472sin1.0472)=4.3481 cm2
