50.3 units squared.
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
-- The ratio of 588 to 1,372 is 0.4286 (rounded) -- A sphere with surface area of 588 has volume closer to 1,340.7 . (rounded)
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
Surface area of a sphere equals 4 times Pi times the Square of its radius. So plugging in the needed radius of 6 makes the formula Area=4*pi*R^2 or 4*pi *6^2 or 4*36*pi and with pi=3.141592654... this becomes 452.3893421... units (144*3.141592654...)
Surface area of a sphere = 4*pi*radius2 Area = 49*pi square units
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
Radius of sphere: square root of (25/4pi) = 1.4 units rounded to nearest tenth Volume of sphere: 4/3*pi*1.4^3 = 11.5 cubic units rounded to nearest tenth
Surface area of a sphere = 4*p*radius2 4*pi*radius2 = 2916 Divide both sides by 4*pi: radius2 = 232.047907 Square root both sides: radius = 15.23311875 cm
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
V = 268.08 cubic inches.

22.564 square inches (rounded)
The surface area is 4 pi r 2. Radius is 7.6cm. This gives you 725.47cm2 rounded up in the hundreds
Surface area of sphere: 4*pi*6 squared = 452.389 square meters rounded to 3 decimal places
637.045 square inches (rounded)
Surface area = 314.2 cm2
