The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
A sphere with a radius of 9 units has a volume of 3,053.63 units3
A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
volume sphere = 4/3 π radius³ → radius = ³√(¾ volume sphere ÷ π) = ³√(¾ × 972cm³ ÷ π) ≈ 6.1cm
Volume of a sphere is 4/3 pi times the cube of its radius.
