Because 4*pi*radius2 is surface area of a sphere
That is correct because the surface area of a sphere is: 4*pi*radius squared
Yes because the surface area of a sphere is 4*pi*radius squared
It is: (pi*radius squared)/4
The surface area is about 153.94 units2 (square units) Surface Area = 4 (pi) r2 For a radius of 3.5 units = 4 x 3.1416 x (3.5)2 units squared = 153.9384 units2
Surface area = 4*pi*radius2
That is correct because the surface area of a sphere is: 4*pi*radius squared
Surface area of a ball or a sphere = 4*pi*radius squared
Surface area of a sphere = 4*pi*radius squared
The surface area of a (closed) cylinder equals the surface area of both bases (the top and bottom), i.e. pi x radius squared (first base) + pi x radius squared (second base), plus the lateral surface area (the surface area of the curved side), i.e. circumference (pi x diameter) x height. Inserting the numbers: SA = pi x (2 m.) squared + pi x (2 m.) squared + pi x 4 m. x 6 m. = pi x 4 m. squared + pi x 4 m. squared + pi x 24 m. squared = 8 x pi m. squared + 24 x pi m. squared = 32 x pi meters squared.
Surface area = 4*pi*radius squared
Surface area of a sphere = 4*pi*radius squared
Surface area of a sphere is: 4*pi*radius squared
Yes and its formula is: 4*pi*radius squared
Surface area of a sphere = 4*pi*(diameter/2)^squared
The surface area of the 'sphere' is four times the area of a 'great circle',or (4 pi) times the RADIUS squared.
It is the formula for finding the surface area of a sphere which is 4*pi*radius2
Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
