What will be the area of the semi-circle of perimeter 3.6 meters? 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 0.77 m2.

Perimeter of semi-circle = 2πr2+2r\frac{2πr}{2} + 2r = 3.6

Solving for r we get, r = 710\frac{7}{10} 

Area of the semi-circle = πr2/2 = 77100\frac{77}{100} = 0.77 m2
