The length of the wall of the tank in feet is 62.8 feet.
<h3>How to solve circumference?</h3>
Circumference is the perimeter of a circular object. Therefore,
circumference = 2πr
where
The fountains pool is enclosed by a circular plastic tank.
The distance from the centre of the pool to the wall of the tank is 10 feet. This is the radius of the circle
Hence,
length of the tank = 2πr
length of the tank = 2 × 3.14 × 10
length of the tank = 20 × 3.14
length of the tank = 62.8 feet.
