First find the radius by dividing 28 by 2*pi which is 4.456338407.
Surface area = 4*pi*4.4563384072 = 249.5549508 or about 250 square inches.
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
The area of circle whose circumference is 100 inches is: 795.8 square inches.
The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
yes heat loss is affected by diameter, circumference and surface area. Heat loss depends on the surface area : volume ratio.......the larger this is the more heat is lost if a cylinder having the same volume but a different surface area...(therefre radius and circumference is different)........the cylinder having the larger surface area will loose heat fastest
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
diameter X pi = circumference circumference X height = area
Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches.
Diameter: 41/pi = 13 inches rounded to a whole number Radius: 13/2 = 6.5 inches Surface area of the sphere: 4*pi*6.5 squared = 530.929 square inches to three decimal places
you divide the surface area by the circumference.
A regulation size 5 soccer ball has a circumference between 68 and 70 centimeters. This translates into a surface area between 1471.865 cm2 and 1559.718 cm2.
The area of a circle with a circumference of 56.52 inches is: 254.2 square inches.
The area of a circle with a circumference of 43 inches is 147.1 square inches.
The area of a circle with a circumference of 9.42 inches is: 7.061 square inches.
If the circumference of a circle is 44 inches, the area is: 154 square inches.
The area of a circle with a circumference of 9.42 inches is 7.061 square inches.
Circumference = 28.2743339 inches. Area = 63.6172512 square inches.
