Question 3
Sudhanshu divides a 7 cm radius plate in two equal parts find out the perimeter of every half plate take (π = 22/7)

Answer 1

The perimeter of every half plate is 22 cm.

Step-by-step explanation:

Sudhanshu divides a 7 cm radius plate in two equal parts.

That means two semi circles are formed.

Perimeter of semi circle = perimeter of every  half plate

Perimeter of every half plate = $\pi r$   [Where r = radius]

Now, plug the values in the formula,

Perimeter of every half plate = $\frac{22}{7} \times 7$

                                               = 22 cm

Hence, the perimeter of every half plate is 22 cm.
