122 x pi = 452.39
The perimeter of the patio is 24 feet.
Square feet are square feet. There is not a measure called radius square feet.
Surface area for a circle is pi * radius squared If the diameter is 25 feet, then the radius is 12.5 feet, and the square footage is pi * 12.5 * 12.5 Or about 491 square feet
225 square feet
divide the square feet by pi that gives you the radius squared find the square root and get the radius
To determine how many patio stones are needed, first convert the dimensions of one stone from inches to square feet. A 24-inch by 24-inch stone is 2 feet by 2 feet, giving it an area of 4 square feet. Dividing the total patio area of 480 square feet by the area of one stone (4 square feet) results in 120 stones needed for the patio.
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.
Radius = 79/(2*pi) = 12.5732405 feet Area = pi*12.57324052 = 496.643 square feet rounded to 3 dp
Since 'radius' usually applies to circles, a circle with a radius of 17 feet would have an area of 907.92 square feet.
To calculate the square footage of a round pool, you can use the formula for the area of a circle: A = πr². For a 28-foot round pool, the radius (r) is 14 feet. Therefore, the area is approximately A = π × (14)² ≈ 615.75 square feet.
