Circle section

An equilateral triangle with side 33 is an inscribed circle section whose center is in one of the triangle's vertices, and the arc touches the opposite side.

Calculate:

a) the length of the arc
b) the ratio between the circumference to the circle sector and the perimeter of the triangle

Correct answer:

x =  29.9277 cm
y =  0.3023

Step-by-step explanation:

a=33 cm r=23 a=23 3328.5788 cm A=60   x=r A° rad=r A° 180π =28.578838324886 60° 1803.1415926 =29.928=29.9277 cm
p=3 a=3 33=99 cm  y=px=9929.9277=0.3023
