Question

22. Find the area of a circle circumscribing an equilateral triangle of side 15 cm. (Take = 314)​

Answer 1

Answer:

235.714 square centimetres

Step-by-step explanation:

We have a circle circumscribing an equilateral triangle of side 15 cm.

The centroid of triangle and the center of circle are same.

To find the radius, we'll find the (radius) distance between center and head of triangle.

Radius = side/√3

= 15/√3

= 8.66 cm

Area = 3.14 * (8.66)^2

= 235.714 square centimetres
