I have a maths question. A pond with a diameter 7.5m requires a fence 1/2 metre from edge what is length of fence?
- KrishnamurthyLv 76 months ago
Radius of pond is 3.75 metres.
Radius of fence is 4.25 metres.
The length of the fence is
8.5 pi metres = 26.7 metres

Length of fencing required: 8.5*pi = 26.7 meters which is the circumference of the fence

New diameter is 8.5 metres (7.5 + 0.5 + 0.5)
Circumference of fence = 3.14 x 8.5 = 26.69m
