Question

four semi circles are drawn taking the sides of a square of side 14 cm as their diameter find the perimeter of given shape​

Answer 1

Step-by-step explanation:

perimeter=p(square)+4p(semicircle)

=4×14+4×π7

=143.92 cm

Answer 2

Given :-

• Side of square = 14 cm.

To Find :-

• Perimeter of given shape .

Solution :-

we know that,

• Radius = Diameter / 2 .
• Perimeter of semi - circle = (1/2) * 2πr = πr .

from image as we can see that, there are 4 semi - circle taken diameter as side of square .

so,

Radius = 14/2 = 7 cm.

then,

→ Perimeter of 1 semi - circle = (22/7) * 7 = 22 cm.

therefore,

→ Perimeter of 4 semi - circles = 22 * 4 = 88 cm. (Ans.)

Hence, Perimeter of given shape is 88 cm.
