Disclaimer: This mulch calculator is for estimating purposes only. Kisser Stone and Garden is not responsible for actual required amounts. but the results are in decimal form with two digits to the right of the decimal point. Linear Calculator (for beds)Enter the length of the sides of the bed in feet and this calculator will return the area in square feet. This calculator will work with rectangular areas (sides a & c are equal as are sides b & d) as well as trapezoidal (two sides of the area must be parallel) shaped area. This calculator uses the formula shown below: Circle Area Calculator (for trees)Enter the radius of a circle, and the calculator will return the area. A radius is a straight line extending from the center of a circle to the circumference or surface (the radius of a circle is half the diameter.) To calculate the sq ft area around a tree:
**Be sure to subtract the area of the tree after calculating your total bed area rather than not including it. Example 113.10 - 3.14 = 109.96 sq. ft. Calculating just as a 5 ft. bed gives a result 31.43 sq. ft. short of the true area.
Circle Area: (square feet)
