The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.
If the diameter is 25 then the radius must be 12.5
When the diameter of a sphere is decreased by 25%, its curved surface area decreases by approximately 43.75%. This is because surface area is proportional to the square of the radius, so a 25% decrease in diameter leads to a 43.75% decrease in surface area.
A cylinder has a diameter of 18 inches and a height of 25 inches has a total surface area of approximately 1,922.65 square inches.
The surface area decreases by 43.75%.
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
The surface area of a softball with a diameter of 12 is about 452.4 square units.
The surface area of a sphere with a diameter of 2.7 inches is about 23 square inches.
The surface area of a sphere with a diameter of 14 inches is about 615.8 square inches.
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
