Step-by-step explanation:
Given : Sides of triangle are 13 cm,14 cm and 15 CM
To Find :find the area of the triangle
Solution:
We will use heron's formula :
Where

Answer:
Step-by-step explanation:
you need the arc length formula .. do you have it?
s = r ∅
s is the arc length in radians but you can make it in degrees just by
using s = 2πr (θ/360)
the angle is 180 for the picture.
so the arc length is just 
r
r= 4
*4 = 12.56637.... approx
