Question

If the side of the square is 14 cm, then find the area of the semi-circle as shown in the figure. Plz

Answer 1

Answer:

Area of half circle or semicircle is 77 sq.cm.

Step-by-step explanation:

Side of square = 14 cm

If we complete the circle, then we will see that it is touching the center of the square.

Length of center from a side of the square = Radius of circle

So length of center from a side of the square = 14/2 cm = 7 cm

Area of a circle = πr² sq.unit

So, area of a half circle or semi circle = (πr²)/2 sq.unit

                                                              = {22/7 × 7²}/2 sq.cm

                                                              = {22/7 × 7 × 7}/2 sq.cm

                                                              = {22 × 7}/2 sq.cm

                                                              = 154/2 sq.cm

                                                              = 77 sq.cm

Ans:- Area of half circle or semicircle is 77 sq.cm.

Hope it helps you =)
