For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
A sphere with a diameter of 6cm has a volume of 113.1 cm3
Volume = 4/3*pi*radius3 = 900 cubic inches By making the radius the subject of the above equation gives the sphere a radius of 5.989418137 inches. Surface area = 4*pi*5.9894181372 = 450.7950449 square inches
The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
the volume of a sphere is 4/3 times pi times the radius of the sphere cubed. V=4/3 Pie r3
There is no equation for the "scale factor" of a sphere. If I assume you to mean how the volume increases with radius then you would use the volume equation for a sphere and calculate volume based on corresponding radii. You could then divide the resultant volumes to give a percentage or factor of how much larger or small one sphere is than another. You'll see that a small change in radius causes a large change in volume due to the volume being a cubic factor of the radius.
The equation is: (4/3)Pie r3The worded equation is: Four thirds Pie multiplied by the radius cubed.answer 2 Archimedes might have immersed the sphere in a liquid, and measured the volume that was displaced.
The volume of a sphere = 4/3*pi*radius3
measure the radius of the sphere and apply the appropriate volume equation: V= (4/3) x (pi) x r3
to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed
Volume of a sphere = 4/3*pi*radius3 measured in cubic units Surface area of a sphere = 4*pi*radius2 measured in square units
Circle.
It's used in finding the volume of a sphere which is: Volume = 4/3*pi*radius3
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere
The volume, V, of a sphere is given by the formula: V = 4/3 * pi * r3. Substituting in r=6 & pi=3.14159 the equation is: V = 4/3 * 3.14159 * 63. The volume is 904.779 in3.
that is pi.there isnt really a variable there it just looks like n
