The total surface area of a sphere when the radius is 4 equals 201.1 units2
The surface area of a sphere with radius 4 is about 201 units2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
1500pi
The surface area of a sphere with a radius of 5m is 314.2m2
Area = 78.54 sq units
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
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.
The surface area of a sphere with a radius of 2 is about 50.27 units2
