Surface area of ball: 4*pi*1^2 = 4*pi square feet
It is 4pi square feet.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
It is the area of its foot-print.
Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
Area = pi x radius x radius (pi = 3.14) Area = 3.14 x 5 x 5 Area = 78.5

Surface area of a sphere = 4πr²A= 4(3.14159) X 1A= 12.56 ft²
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
37.69911184 rounded to 38 square feet
Use the formula area = pi times radius2 to get the area. The radius is half the diameter. A foot is 12 inches, a square foot is 144 square inches.Use the formula area = pi times radius2 to get the area. The radius is half the diameter.

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.
Area of a circle = pi times radius squared
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
the hoof.
Area of any circle is: pi times radius squared
Curved surface area = 2*pi*radius*height = 2*3.14*1*3 = 18.84 square feet Area of the 2 ends = 2*pi*radius2 = 2*3.14*12 = 6.28 square feet Total surface area = 18.84+6.28 = 25.12 square feet.
