This math topic focuses on calculating the surface area of spheres, an advanced geometry concept involving 3D shapes. The problems require applying the formula for the surface area of a sphere \( SA = 4\pi r^2 \), where \( r \) is the radius. Problems entail determining the correct computation given different sphere radii (2, 4, 5, and 3 units). Additionally, there are multiple-choice options where students must choose the correct formulation among other expressions, which may be distractions incorporating irrelevant calculations, such as volume expressions or unrelated geometric formulae.
