Question

A wire is in the form of a square of side 11cm each is
reshaped and bent into the form of a circle. Calculate the
diameter of the circle so formed.
answer= pls

Answer 1

Answer:

diameter = 14 cm

Step-by-step explanation:

perimeter of square = perimeter of circle

perimeter of square = 11×4 = 44 cm

2πr = 44

r= 7cm

so diameter will be 7×2 = 14 cm

Answer 2

each side of square is (a) = 11cm

area of a wire in form of square = a² = (11)² = 121cm

when wire is reshape and bent into the form of a circle then,

area of a wire in form of square = area of a wire in form of circle

121cm = π R²

121 = 22/7 R²

R² = 121(7/22)

R² = 38.5

R = √38.5
