Question

14

Answer 1

Answer:

The area of the semi-circle = 76.93 square units

Step-by-step explanation:

Explanation:-

Given that the diameter of the circle d= 14

We know that Area of the circle

                   A = πr²

The radius of the circle

             $r = \frac{d}{2} = \frac{14}{2} = 7$

The area of the semi-circle

                      $A = \frac{\pi r^{2} }{2}$

                     $A = \frac{\pi (7)^{2} }{2} = \frac{49\pi }{2}$

Put π = 3.14

The area of the semi-circle

                  $A = \frac{3.14 X 49}{2} = 76.93 square units$
