Find the diameter of a sphere with a surface area of 19677 square centimeters. Surface Area of Sphere = 4Ï€r^2 19677 = 4Ï€r^2 To find the diameter, we need to find the radius first. Rearranging the formula, we have: r^2 = 19677 / (4Ï€) r^2 = 4961.25 r â‰ˆ âˆš4961.25 r â‰ˆ 70.45 cm Now, we can find the diameter by multiplying the radius by 2: Diameter = 2 * r Diameter â‰ˆ 2 * 70.45 Diameter â‰ˆ 140.9 cm Therefore, the diameter of the sphere is approximately 140.9 cm.
