Question

A wire in the shape of a square of side 11 m is recent into the shape of a circle. Find the area of the circle

Answer 1

Answer:

Area of circle is 154 m^2.

Step-by-step explanation:

Side of square of wire = 1 1 m

Perimeter of this wire square = 4 ☓ 11 = 44 m.

Now

Perimeter of square = length of wire.

Circumference of circle = length of wire = 44m

2 ☓ pi ☓ r = 44

pi ☓ r = 22

22/7 ☓ r = 22

r = 7 m.

Area of circle = pi ☓ r^2

Area of circle = 22/7 ☓ 7 ^2

Area of circle = 154 m^2
