That's actually a cylinder.
8 inches = 2/3 foot
The volume of a cylinder is (pi) (radius)2 (height) = (pi) (5)2 (2/3) = 52.36 cubic feet (rounded)
The area of a circle is the number pi (3.14159...) times the square of the radius. The radius is half the diameter. So if the diameter is 8 inches, the radius is 4 inches. Squaring that gives us 4 x 4, or 16 square inches. Multiplying 16 by pi equals an area slightly larger than 50.26 square inches.
A cylinder with a diameter of eight inches and a height of five inches has a surface area of 226.2 square inches.
area of a circle = pi times radius squared = 3.1415... x (half of diameter of 8 inches)2 = 3.1415... x 42 = 3.1415... x 16 = 50.26548... square inches
If you divide eight by pi, you get 2.54647909 as the diameter. If you divide eight by 3.14 (simplified pi), you get 2.54777070 as the diameter.
Draw two diameter lines, then draw a circle inside the circle.
4 inches
If the area of a circle is about 28 square inches the diameter is: about six inches (5.971).
16 inches
4 inches The radius of a circle is always half of its diameter (so 8in/2 = 4 in).
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
The area is 2,640 square inches for a 58-inch diameter circle.
If you mean a cylinder then it is: pi*4*4*0.25 = 12.566 cubic feet to 3 decimal places
The area of a circle is the number pi (3.14159...) times the square of the radius. The radius is half the diameter. So if the diameter is 8 inches, the radius is 4 inches. Squaring that gives us 4 x 4, or 16 square inches. Multiplying 16 by pi equals an area slightly larger than 50.26 square inches.
1,728 cubic inches = 1 cubic foot 68 cubic inches = 0.03935 cubic foot (rounded)
