The surface area of a sphere is 4(pi)r2. Thus,
4(pi)r2 = 848 pi, divide both sides by 4 pi
r2 = 212, take the square root to both sides and let 212 = 4*53
r = √(4*53)
r = 2√53 units.

The area of a sphere is Area = 4(pie)r^2 If this is a cylinrical tank with spherical ends you need the length. The area of the cylinder part is (pie)r^2 x length then add to area of sphere
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 sphere is : A= 4*pie*r^2
4/3 pie(7exponent3)
the volume of a sphere is 4/3 times pi times the radius of the sphere cubed. V=4/3 Pie r3
