An isosceles triangle (two sides equal) is placed on top of a square as shown in the picture. if the two equal sides of the triangle are 17cm long and the square is 27cm on each side, what is the perimeter of the figure?

where is the picture

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
