Circle section

Equilateral triangle with side 33 is inscribed circle section whose center is in one of the vertices of the triangle and the arc touches the opposite side.

Calculate:

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

Correct result:

x =  29.9277 cm
y =  0.3023

Solution:

a=33 cm r=32 a=32 3328.5788 cm A=60  x=r A rad=r A π180 =28.5788383249 60 3.1415926180 =29.928=29.9277 cm
p=3 a=3 33=99 cm  y=xp=29.927799=0.3023
