The length of wire used to fence a circular garden will be equal to the circumference of that circular garden, then :

Length of wire = 396 m

Circumference = 396 m

2πr = 396

2×${ \large{ \frac{22}{7}}}$×r = 396

r = ${ \large{ \frac{396×7}{2×22}}}$

r = 63

Radius = 63 m

Diameter = 2×63

Diameter = 126 m

Answer 2

Answer:

Answer is 126

Step-by-step explanation:

lenth of circular garden(circumference) = 396 m

2πr = 396

r = 396÷2π

r = 396×7÷ 2× 22

r = 63 m

Diameter = 2 × r

= 2 × 63

= 126 m
