The distance from the centre of a circle to any point on the boundary is called the radius. The radius is half of the diameter; 2r=d 2 r = d . The line segment that joins two points on the circle is a chord. Every diameter is a chord, but not every chord is a diameter.
What are mathematically similar cylinders?
This is because one definition of a circle is all points in a plane the are a given distance (the radius) from a given point (the center). In your case, radius 1 means the distance from the center to the circumference is 1 (inch, centimeter, foot, yard, etc.).
Why is a sphere 4 3?
Area is a measure of how much space there is inside a shape. Calculating the area of a shape or surface can be useful in everyday life – for example you may need to know how much paint to buy to cover a wall or how much grass seed you need to sow a lawn.

The density of an object can be calculated using the equation density = mass / volume. This calculation gives a numerical value which describes the amount of mass that is confined within a specific volume of an object.
What is 1 radius?
Because π is irrational, it has an infinite number of digits in its decimal representation, and does not settle into an infinitely repeating pattern of digits. There are several proofs that π is irrational; they generally require calculus and rely on the reductio ad absurdum technique.
How do you find the radius of a cylinder?
The pi is an irrational number and does not have an exact value. In general, the value of π is considered as 3.14 or 22/7 for various mathematical calculations.

William Jones, FRS (1675 – 1 July 1749) was a Welsh mathematician, most noted for his use of the symbol π (the Greek letter Pi) to represent the ratio of the circumference of a circle to its diameter.
How do you calculate dimensions?
The volume of a cylinder with base radius 'r' and height 'h' is, V = πr2h. If its base diameter is d, then we have d = r/2. Substituting this in the above formula, we get V = πd2h/4. Thus, the formula to find the volume of a cylinder with the diameter (d) and height(h) is V = πd2h/4.

If you Google the weakest shape, the most common answer is the circle. Many variables will factor here as well. As it turns out, there really is no simple, one-size-fits-all answer to the question. Knowing if we need strength for support or containment is an example of what needs to be known to answer the question.
Why is pi infinite?
A four-cylinder engine fits well in smaller cars and offers great fuel efficiency, but it lacks the power of a six-cylinder. Adding turbocharging improves fuel economy and performance without taking up the space of a larger engine. A six-cylinder has more power, but it also uses more gas.

The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.
