Question

Kritika had a wire in the shape of a circle of radius
4 cm. She wanted to bent the same wire in the shape
of a square of side 5 cm. Will she be able to do so?
Justify your answer.
(Explain your answer)​

Answer 1

circumference of a circle = 2π r = 2r * 4 cm = 25.13 cm.

so she has 25.13 cm of wire.

perimeter of a square = 4 * side = 4 * 5cm = 20 cm.

since she have more then 20 cm of wire, yes she will be able to make the square.
