Answer 1

Answer:

(22/7) * 7 *7 = 154 cm²

Step-by-step explanation:

As we know by angle sun property, sum of all the three angles of a triangle is 180° . If we combine all the angles of his triangle, it gives 180°. On joining the three corners, we get a circle of shaded area with radius 7 cm.

And hence it is a complete circle because in circle also. the angle at its center is 180°.

So the area of shaded region is = pi * r²

                                                     = 22/7 * 7 * 7

                                                     = 154 cm²
