Solution

The correct option is C $50 π m$
Diameter of smaller garden = $50 m$
$∴$ radius of smaller garden, r = $25 m$
Now,
Edging needed to outline the smaller garden= it's perimeter
= 2πr = $2 π \times 25 m = 50 π m$

The correct option is C 50π mDiameter of smaller garden = 50 m ∴ radius of smaller garden, r = 25 m Now, Edging needed to outline the smaller garden= it's perimeter = 2πr = 2π×25 m=50π m
