You are correct my friend! Surface Area of a Sphere is indeed = 4(pi)r^2 and that is also equal to Circumference times Diameter!

Surface area of a sphere with a radius of 9?
The sphere's surface area is ~1,017.9 square units.
Is the surface area of a sphere with a radius of 4.5?
Surface Area = 254.47 square units
What is the surface area of a sphere with the radius of 6.6?
Surface Area = 547.39 units square
What is the radius if area of a sphere is 4 meter square?
If the surface area of the sphere is 4 m2, the radius is 0.5642 metres, approx.
If the surface area of a sphere is increased by a factor of 4 what is the change in the length of the radius of the sphere?
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
If the radius of a sphere doubles does its surface area double?
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
What is the surface area of a sphere with radius 6?
The surface area of a sphere with radius 6 is: 452 square units.

What is surface square footage of 90' sphere?
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 thesphere'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)
What is the surface area of sphere with a radius of 12 units?
Surface area of the sphere = 4*pi*122 = 1809.557368 square units
