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

the volume of a sphere is 4/3 times pi times the radius of the sphere cubed. V=4/3 Pie r3
Formula for surface of sphere is 4 X pi X radius squared.4 x 4squared = 64 pie = 201.0622498so your answer is64 pie or 201.0622498(Either would work)
to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed
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
surface area of a spere=4*pie*r2 when r (radius)=5 pie=22/7 surface area=4*22/7*5*5 =2200/7 =314.2 dm2

there would be no" lateral" surface to a sphere because it is round , only with a cube ,pyramid or rectangular object would you have lateral surface,although it is still possible to determine the surface area and volume of a sphere, the formula to calculate the area of a sphere is 4x pie x radius squared, to calculate the volume the formula is 4x pie x radius cubed divided by 3, to calculate a hemisphere you would divide the answer in half.
The pie radius refers to the distance from the center of a pie to its edge, essentially defining the size of the pie. In mathematical terms, it is half of the diameter of the pie. The radius is crucial for calculating the area of the pie, which can be determined using the formula A = πr², where "A" is the area and "r" is the radius.
r = 4.762 units
Surface area of sphere is : A= 4*pie*r^2
volume is equal to four thirds pie times the radius cubed.
