How many square feet are there in a patio which is in the shape of a half circle and whose radius is 6 foot 3 inches?

Well, If the radius is 6.25 feet, we can use the equation πr2, and assuming that pi (π) is 3.1415, we square 6.25 to get 39.0625, then multiply this by π to get 122.714844 ft2, which we multiply by 1/2 because this is a half circle, not a full circle. Once we multiply by 1/2, we get 61.357422 ft2. So, there are 61.357422 square feet in a patio which is the shape of a half circle and whose radius is 6.25 feet or 6 foot 3 inches.
