The LLR (also called Vortec 3700), is a straight-5 DOHC engine produced from 2007 through 2012. It displaces 3.7 L; 222.9 cu in (3,653 cc), courtesy of a larger 95.5 mm (3.76 in) bore while keeping the 102 mm (4.02 in) stroke. The LLR also corrected the head issue found in the L52.
where C is the circumference of a circle, d is the diameter, and r is the radius.More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
In mathematics, the Leibniz formula for π, named after Gottfried Wilhelm Leibniz, states that = + + = = +,. an alternating series.. It is sometimes called the Madhava–Leibniz series as it was first discovered by the Indian mathematician Madhava of Sangamagrama or his followers in the 14th–15th century (see Madhava series), [1] and was later independently rediscovered by James Gregory in ...

In Measurement of a Circle written circa 250 BCE, Archimedes showed that this ratio (written as /, since he did not use the name π) was greater than 3 10 / 71 but less than 3 1 / 7 by calculating the perimeters of an inscribed and a circumscribed regular polygon of 96 sides. [9]
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
