The formula for its volume equals: volume = (4/3) × π × r³ Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point.
WebOct 14, 2024 · 1 Answer. Your intuition is correct. If an n -ball of radius n has volume V n r n, increasing r by d r adds a thickness- d r shell of volume d r times the ball's surface, i.e. the surface is d ( V n r n) / d r = n V n r n − 1. This ( n − 1) -dimensional measure is of what we call the ( n − 1) -sphere, so you've proven the fact that the 4 ... WebThere are posters with formulas for surface area of a cylinder, cone, & sphere.
