Question

verify the surface area of a sphere 4 pi r^2

Answer 1

Answer:

Area is the product of 2 length measures. If we divide a sphere into 2 hemispheres. Area of 1 hemisphere = base length x height. If we unfold the hemisphere, base length. = 2 pi r & height = r. => area of 1 hemisphere = 2 pi r * r = 2 pi r² Area of 2nd hemisphere = 2 pi r² So total area of Sphere = 2 pi r² + 2 pi r²
