WebEXAMPLE 1. Find the cross-sectional area through the center of a sphere that has a radius of 5 m. Solution: Since the cross-section passes through the center of the sphere, we know that the section will have the same diameter and radius as the sphere. Therefore, we can use the formula for the area of a circle with the given radius. WebOn sait que la forme standard de l’équation d’une sphère est ( 𝑥 − 𝑎) + ( 𝑦 − 𝑏) + ( 𝑧 − 𝑐) = 𝑟, où ( 𝑎; 𝑏; 𝑐) est le centre et 𝑟 est la longueur du rayon. On connaît ici les coordonnées du centre de la sphère et, par conséquent, on peut en déduire que 𝑎 = 1 1, 𝑏 = 8 et 𝑐 = − 5. On ...

Manufacturers derive all rayon fabrics from natural materials like wood pulp and cotton. But the manufacturing process requires certain chemicals to treat rayon fibers which differentiate the final product. Rayon is soft, breathable, and comfortable to wear.
