Answer:

Step-by-step explanation:

The pond that you want to construct is circular. The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

You want the pond to cover an area of of 300ft^2. Therefore,

A = 3000

To determine the radius of the pond, it becomes

3000 = 3.14r²

Dividing the left hand side and the right hand side of the equation by 3.14, it becomes

3.14r²/3.14 = 3000/3.14

r² = 955.414

Taking square root of the left hand side and the right hand side of the equation, it becomes

√r² = √955.414

r = 31 ft
