Question

Find the area of a circle circumscribing an equilateral triangle of side 15 cm. [Take = 3.14]​

Answer 1

Step-by-step explanation:

Let the radius of a circle be r ...

This circle also circumscribing the equilateral triangle of a side=15cm...

Hence , The relation between radius and side of a triangle ; We get ,

= r = 15 / √3 ..

Area of the circle = π ( 15/√3 ) ^2

=. { 3.14 × 225.3 }

= 235.5 cm^2b.
