Technical Math: Area & Volume of a Sphere

 

** 

Relevant Material: "Applications of a sphere's area and volume include packaging, engineering, and design, such as calculating how much material is needed for a spherical container (area) or how much it can hold (volume). Other uses include architecture for domes, physics for buoyancy, and biology for understanding cell size limitations. 
Volume applications 
  • Packaging and manufacturing: Determines the capacity of spherical containers for items like ball bearings, medicine capsules, or food products.
  • Engineering: Used to calculate buoyancy for watercraft like submarines and to determine the amount of air needed for objects like hot air balloons.
  • Cooking: Helps in measuring ingredients and understanding the spatial relationship for preparing spherical foods like meatballs or cookies.
  • Architecture: Calculates the internal space of domes and other spherical structures.
  • Biology: Helps model the volume of a cell and understand how the surface area to volume ratio (
    SA∶Vcap S cap A colon cap V
    ) limits its size.     
Surface area applications 
  • Packaging and manufacturing: Calculates the amount of material needed to create spherical items, such as balls or capsules.
  • Engineering: Used in designing objects like car engines or gas tanks to determine the amount of sheet metal required.
  • Architecture and design: Helps in calculating the amount of material needed to clad buildings or design structures like domes.
  • Physics: Used to understand how objects lose or gain heat, as heat exchange is proportional to surface area.
  • Biology: Explains how the surface area to volume ratio affects cell growth and function.
  • Aeronautics: Used to optimize the design of aircraft wings to reduce drag and increase lift. .." (Google)

Technical Math: Sine Law

Image
  **  Relevant Material : "  The sine law is used in real-life applications like   navigation   to determine positions,   surveying   to map land,   astronomy   to calculate distances to stars, and   engineering   and   architecture   to design and build structures. It is also applied in fields such as physics for analyzing forces and projectile motion, and even in computer graphics.   Navigation and Surveying Navigation:  Sailors and pilots use the law of sines to determine their location and heading by triangulating their position from known reference points. Surveying:  Land surveyors use it to calculate distances and positions for mapping and to determine the height of objects like cliffs by measuring angles from different points .   Engineering and Architecture Structural design:  Architects and engineers use the law of sines to calculate angles and dimensions for building structures, ensuring...
