Length of chord = 10cm
Distance from centre = 12cm
By Pythagoras theorem,
h×h = (p×p) + (b×b)
h^2 = 10^2 + 12^2
h^2 = 100 + 144
h^2= 244
h = √244
h = 15.62 = 16 cm
Therefore ,
r = 16 cm
Area of circle = πr^2
= 22/7 × 16×16
= 804.25 cm^2
Hope this helps you!

According to the data
the information froms a triangle
● the height of the triangle is 12cm
● the base of the triangle is 10cm
》Area of a triangle = 1/2 × base× height
= 1/2 × 10 × 12
= 1 × 5 × 12 =60cm^2
♡ Area of the triangle formed = 60cm^2
