The diameter of a circle is double in magnitude as compared to the radius of the circle. Answer and Explanation:1 Given that a circle is inscribed in a square with an area of {eq}121 \rm ~ft^{2}. {/eq} $$\begin{align...
The theory of areas of plane figures bounded by simple curves —that is, curves that do not intersect themselves—can be constructed as follows. Let us consider every polygon that can be inscribed in and every polygon that can be circumscribed about a figureF.It should be noted, incidentally...

Let us consider every polygon that can be inscribed in and every polygon that can be circumscribed about a figure F. It should be noted, incidentally, that the area of a polygon can be calculated by calculating the area of an equivalent square obtained by making suitable rectilinear cuts and...
Scrapers with a surface area circumscribed by a circumferential eiskratzkanteThe ice scraper has a scraper edge (2), which encloses a circular surface (5). The edge is formed by a circular, elliptical, rectangular, or square cylinder (3). A rounded grip (4) is located opposite to the ...
Here,Ais the area,ais the length of the apothem,nis the number of sides, andsis the length of one side of the polygon. Answer and Explanation:1 The problem gives us an equilateral triangle. The circle inscribed in this triangle has a radius of2units. This can ...
After Gaussian filtering, the contour of the circumscribed rectangle of the measured leaf in the image is obtained, the relationship between the edge and the area is analyzed, and the error correction parameter is calculated for use by the error correction module. 2.2.2. Distortion Correction ...
Find (i) the area of triangle ABC (ii) the altitude of triangle ABC on the base with length 9 (iii) the radius of the inscribed circle of triangle ABC (iv) the radius of the circumscribed circle of triangle ABC Find the area of the following triangle : ...
Finally, the area computation based on the minimum circumscribed circle and the maximum inner circle of the edge is provided. The experiment results prove the system reliability, and the general significances of the proposed algorithms. Introduction The standard gas valve allows precise control of ...
