2 pi r times the circumference sqaured. then take this and find out its square root.
This however, only works if you have the circumference.
If you have both the volume and the height, you can find the formula for the radius by solving the following literal equation for "r":
V=1/3 r^2(3.14)(H)
r=(3V/pi H)square root
The mass of a sphere is 4/3*pi*r3*d where r is the radius of the sphere and d is the density of the material of the sphere.
Dilution factor is the final volume / aliquot volume. Aliquot volume is the measure of sub volume of original sample. Final volume is the total volume. Dilution factor =final volume /aliquot vol. for example ; what is the df when you add 2ml sample to 8m??? total vol is 2+8=10 DF=total vol/aliquot. 10/2=5 So 5 is dilution factor
That's a fairly easy calculation.The Sun is 93,000,000 miles away. The formula for the area of a sphere is 4/3*pi*r^2The cross-sectional area of the Earth is a circle with a radius of about 4,000 miles. The formula for the area of a circle is pi*r^2.Google can be used as a calculator! The answer is(pi * (4000^2)) / ((4 / 3) * pi * (93 000 000^2)) = 1.38744364 × 10-9So, 0.0000001387%.In technical terms, that's "Not much!"Comments: Unfortunately, this answer uses the wrong formula for the surface area of a sphere. I calculate the correct answer to be about 0.00000004.5 %.Also, it doesn't deal with the point about how much energy reachesthe surface of Earth.Surface area of a sphere is: 4 "pi" (radius)2 .
A millimetre is a unit of distance. A cubic foot is a unit of volume. The two units are therefore incompatible.
h = height, B = area of base, v= volume h = 1/3 B * v formula
Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic units.
Volume=(4/3)π(radius of sphere)^3
me...
The volume for a sphere is: 4πr3 3 the π is pie (3.14)
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
It depends on the shape. The formula for the volume of a sphere is quite different from that for the volume of a cube.
Because when working out volumes the answer is given in cubic units and the radius in the formula for finding the volume of a sphere is cubed: Volume of a sphere in cubic units = 4/3*pi*radius3
Volume of a sphere = 4/3*pi*radius3 in cubic units.
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
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)
Volume = 4/3*pi*radius3
Volume of a sphere = 4/3*pi*radius3 and measured in cubic units
