Spike's Calculators

Calculate the area and perimeter of a stadium.

This calculator uses metres for measurements.

A stadium here is an oval shape consisting of a rectangle with two semi-circles at the opposing ends.

If the diameter length is equal to the overall length you are calculating for a circle area and circumference!!

- the overall length of the stadium in metres
- the diameter length of the stadium in metres
- decimal precision, the number of digits after the decimal point

- the area of the stadium in square metres
- the area in square feet
- the area in square inches
- the perimeter of the stadium in metres
- the perimeter in feet
- the perimeter in inches

A = 𝝅/4D²+LD P = 𝝅D+2L where A is the area of the kite D the diameter length L the overall length minus the diameter P the perimeter of the kite

one metre (m) = 3.28083989501312 feet (ft) one metre (m) = 39.3700787401575 inches (in) one square metre (m²) = 10.7639104167097 square feet (ft²) one square metre (m²) = 1550.0031000062 square inches (in²)
