The radius is one half the diameter so if the diameter is 8 inches then the radius is 4 inches.
Given the information in the question, there is no need for any inequality. the flat surface can be described as an equality. Outer diameter = one and a half inches => outer radius = 0.75 inches. Inner diameter = three fourths inches => inner radius = 0.375 inches. Area = pi*(0.752 - 0.3752) square inches. So one possible set of inequalities is 0 < area < 1,000,000,000 sq inches!
Assuming a circle with a diameter of one half inch, A = 2Ï€r so the area in square inches would be half of pi or about 1.57 in2.
Any number you like. You can have a tiny circle with a tiny diameter or a huge big circle with a big diameter. The diameter is simply the "width" of the circle. It is the length of the line from one side to the other which passes through the centre.
One yard is 36 inches - whether in diameter or otherwise.
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
The radius is one half the diameter so if the diameter is 8 inches then the radius is 4 inches.

one half yard?
as big as your mama
6 inches, smart one
It's one half inch (.50) in diameter.
Weaver's beams were two and one half inches in diameter.
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
Assuming a circle with a diameter of one half inch, A = 2Ï€r so the area in square inches would be half of pi or about 1.57 in2.
The diameter of a circle represent the distance across it when divided in half. 1 millimeter equals .04 inches (rounded to one significant figure). Therefore 12 mm equals .05 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.
