The surface area of a sphere is (4 pi) x (radius of the sphere)-squared.
We're not completely sure of what a "90' sphere" is. If you're saying that the
sphere's diameter is 90-ft, then its radius is 45-ft, and its surface area is
(4 pi) x (45-ft)-squared = 25,446.9 square feet, or 2,827.4 square yards. (both rounded)
8100'
Assuming the room is 60 ft by 90 ft (the question does not say so), the area would be 60*90 = 5400 square feet
For basic computations, consult Google.90 inches x 59 inches in square feet=>(90 inches) x 59 inches = 36.87500 square feet36'10 1/2" square or 36.875square foot
It is the surface area, expressed in square feet, of any two or three dimensional shape.
Lateral surface area = 75.39822369 or about 75 square inches Total surface area = 89.53539063 or about 90 square inches

You can't calculate linear footage based on square yardage alone. If you meant square footage it will cover 810 sq. ft..
To get square footage you multiply the width by the length. In this case 90 times 50 equals 4500 sq. feet

The square footage is indeterminate without knowing the angles at the corners of the rectangle. Using one square corner ( 90 Degrees ) the area is about 6,430 square feet.
One floor would be 30 x 90 = 2700 square feet. Since it has two stories, it has 2 x 2700 = 5400 square feet.

Ah, what a lovely question! To find the square footage of a room, you simply multiply the length by the width. So, for a 9x10 room, you would multiply 9 by 10 to get 90 square feet. Isn't that just delightful? Happy painting!
The question is seriously flawed and so cannot be answered. Volume cannot be measured in cm, nor can surface area be measured in cm. Furthermore, a radius of 90 cm, volume of 200 cubic cm and surface area of 180square cm are inconsistent. No two of them can refer to the same sphere!That is, with the appropriate units,radius = 90 implies volume � 200, surface � 180volume = 200 implies radius � 90, surface � 180surface = 180 implies radius � 90, volume � 200.
