Question

the area of a circle interrupted in a equilateral triangle is 154 cm square find the perimeter of the triangle

Answer 1

We know that,
πr²=area of a circle then the equation is

then,

πr²=154
=>22/7×r²=154
=>22×r²=22
=>r²=1
=>r=1

We know that,
2πr=diameters of a circle

then,

2πr
=2×22/7×1
=44/7
=6.285 approx.

hope it helps
