4 pie ft. 2
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
The surface area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For an 18-foot circle, the radius is 9 feet (half of 18 feet). Plugging this into the formula, the surface area is ( A = \pi (9)^2 ), which equals approximately 254.47 square feet.
To calculate the surface area of a circular spa, you can use the formula for the area of a circle: ( A = \pi r^2 ), where ( r ) is the radius. For a spa with a 12-foot diameter, the radius would be 6 feet (half of the diameter). Plugging this into the formula gives you ( A = \pi (6)^2 \approx 113.1 ) square feet. Therefore, the surface area of the spa is approximately 113.1 square feet.
Area of a circle = pi*radius squared
If 75 feet is the circumference of the pond then its radius works out as 12 feet rounded to the nearest whole number and its surface area is pi*12^2 which is 144*pi square feet.
Surface area of a sphere = 4πr²A= 4(3.14159) X 1A= 12.56 ft²
Surface area of ball: 4*pi*1^2 = 4*pi square feet
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.

The surface area of an average adult human foot is about 1.5% of the total body surface area. This means that the foot occupies a relatively small percentage of the body's overall surface area.

Area of a circle = pi times radius squared
To calculate the surface area of a 15-foot round pool, you can use the formula for the area of a circle: A = πr². The radius (r) of the pool is half the diameter, so r = 7.5 feet. Using π (approximately 3.14), the surface area is A = 3.14 × (7.5)² ≈ 176.71 square feet.
