Question

in the given figure triangle pqr is an equilateral triangle of side 8 cm and the d e f are the centres of circular arcs each of radius 4 cm find the area of shaded region ( use phy is 3.14 and root 3 is 1.732

Answer 1

Answer:

2.592 cm²

Step-by-step explanation:

Given that it is an equilateral triangle

⇒ Each angle is 60º

Find the area of the 3 sectors:

Area = 3 x 60/360 x πr²

Area = 3 x 60/360 x π(4)²

Area = 25.12 cm²

Find the area the triangle:

Area = √3/4(sides)²

Area = √3/4 (8)

Area = 27.712 cm²

Find the area of the shaded region:

Area = 27.712 - 25.12 = 2.592 cm²

Answer: The area is 2.592 cm²
