sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector. In the diagram, θ is the central angle in radians, r the radius of the circle, and L is the arc length of the minor ...
Comparing the area of sector and area of circle, we get the formula for the area of sector when the central angle is given in radians. This formula allows us to calculate any one of the values given the other two values. Worksheet to calculate arc length and area of sector (radians) ...
Hero’s argument is a little peculiar. We need to know that the example taken is general and not just an odd instance where half the area of the circle, taking the circumference as 3·diameter, equals (, withbequal to the diameter andhthe radius. In any case, one would quickly see t...

keeping the same length in the compass, place the compass pointer at point q. similarly, draw two arcs above and below the line keeping the compass pointer at q. step 5: mark the points where the opposite arcs cross as x and y. step 6: using a ruler, draw a line passing across x...
An MOS/LSI semiconductor chip for providing the functions of an electronic calculator or digital processor includes a data storage RAM, a ROM for program instruction storage, an arithmetic unit for performing operations on data, and control circuitry for defining the functions of the machine in resp...
In the diagram, θ is the central angle in radians, r the radius of the circle, and L is the arc length of the minor sector. A sector with the central angle of 180° is called a half-disk and is bounded by a diameter and a semicircle. Sectors with other central angles are ...
is any natural number. for example; a line segment of length 10 cm is divided into two equal parts by using a ruler as, mark a point 5 cm away from one end. 10 cm is divided into two 5 cm line segments. similarly, a line segment of length 15 cm can be divided in the ratio 2...
