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.

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

###### Area of the Half Stadium
Square Metres
Square Feet ft²
Square Inches in²
Metres m
Feet ft
Inches in

#### Calculation

1. the overall length of the stadium in metres
2. the diameter length of the stadium in metres
3. decimal precision, the number of digits after the decimal point

#### Results

1. the area of the stadium in square metres
2. the area in square feet
3. the area in square inches
4. the perimeter of the stadium in metres
5. the perimeter in feet
6. the perimeter in inches

##### Formula
```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
```

##### Conversions
```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)
