I'll assume 23 is diameter because it's not specified. Circumference is 2 pi r,
so r is 23/2 which is 11.5. 11.5 x 3.14159 x 2 = 72.26in
A circle with an 8-inch diameter has a perimeter of 25.1 inches.
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
19.63 square inches are in the area of a 5-inch diameter circle.
The area of a 3-inch diameter circle is about 7.068 square inches.
That would depend on what you mean by "five inch circle".
circumference = 17pi inches
A 1.25-inch diameter circle contains 1.227 square inches.
A circle with an 8-inch diameter has a perimeter of 25.1 inches.
A 4.75-inch diameter circle contains 17.72 square inches.
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
Area of a circle = pi*radius2 inches
The circumference of an 8 inch circle is: 25.13 inches(diameter x Pi = circumference).
The area of a 3-inch diameter circle is about 7.068 square inches.
19.63 square inches are in the area of a 5-inch diameter circle.
That would depend on what you mean by "five inch circle".
Area of circle is pi*radius*radius. hence area of 1.5 inch circle is 7.065 square inches.
A circle with a 23 inch diameter has am area of 415.4756 sq inches (to 4 dp).
