How is the cross-sectional area of a sphere calculated?

Web1 Answer. You have two equations: x 2 + y 2 + z 2 = 1 and x + y + z = k. The coordinates here relate to your new coordinates as follows: The first two columns are your u 1 and u 2, the last is the normal vector of the plane. Now use this to … WebUse the formula that the area of a disk of radius r is πr2: the area of the cross section is cross section at x = π(√1 − x2)2 = π(1 − x2) Then integrate this from − 1 to + 1 to get the volume: volume = ∫right left area of cross-sectiondx = ∫ + 1 − 1π(1 − x2)dx = π[x − x3 3] + 1 − 1 = π[(1 − 1 3) − ( − 1 − ( − 1)3 3)] = 2 3 + 2 3 = 4 3 Exercises WebSep 19, 2024 · Cross-sectional area is determined by squaring the radius and then multiplying by 3.14. For example, if a tree is measured as 10″ DBH, the radius is 5″. Multiplying 5 by 5 equals 25, which when multiplied by 3.14 equals 78.5. Thus, the cross-sectional area of a 10″ DBH tree is 78.5. how far is buhl from twin falls
