The surface area of a sphere with radius 4 is about 201 units2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
1500pi
The total volume of the new sphere will be 4 times less than the sum of all eight individual volumes. The total surface area will be about half than the total surface area of all individual balls.
The total surface area of a sphere when the radius is 4 equals 201.1 units2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
Area = 78.54 sq units
1500pi
Total surface area = 864 cm2Area of each face = 1/6 of that = 144 cm2Length of the side of the cube = sqrt(144) = 12 cmVolume = 123 = 1,728 cm3
A surface area of 804.2 cm2
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
The total volume of the new sphere will be 4 times less than the sum of all eight individual volumes. The total surface area will be about half than the total surface area of all individual balls.
