plz fast plz​

Answer 1

Answer:

Diameter of garden = 28cm

so radius of garden = 28 = 14cm

2

Circumference of circle = 2πr

2 × 22 × 14

7

Circumference of circle is 88 cm.

Rope was to be rounded around the field 3 times

Rope needed = Circumference of circle × 3

= 88 × 3

= 264cm

So,the length of the rope needed is 264 cm.
