Question

a wire is in the form of a rectangle and the perimeter of that rectangle is 176 m. the wire is straightened and bent in the form of a circle. find the radius of the circle and area of the circle​

Answer 1

Step-by-step explanation:

Length of wire = circumference of circle

circumference of circle = 176

2pieR = 176

2×22/7×R = 176

44/7×R =176

R = 176×7/44

R = 28

So , radius of circle = 28

Area of circle = pie×R×R

= 22/7×28×28

= 2464 square cm

Answer 2

Answer:

LENGTH OF WIRE =CIRCUMFERENCE OF CIRCLE

circumference of circle = 176

circumference of circle = 176 2π r = 176

circumference of circle = 176 2π r = 176 2×22/7×R = 176

circumference of circle = 176 2π r = 176 2×22/7×R = 176 44/7 × R = 176

circumference of circle = 176 2π r = 176 2×22/7×R = 176 44/7 × R = 176 R=176×7/44

circumference of circle = 176 2π r = 176 2×22/7×R = 176 44/7 × R = 176 R=176×7/44R=28 CM

SO, RADIUS OF CIRCLE = 28

AREA OF CIRCLE = π×R×R

=22/7×28×28

=2464² CM
