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

What is the formula for the mass of a sphere?
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.
That the height of the cone of maximum volume that can be inscribed in a sphere of radius 12cm is 16cm?
The height of the cone of maximum volume that can be inscribed in a sphere of radius 12 cm is not 16 cm; it is actually 16 cm when considering the relationship between the cone's dimensions and the sphere's radius. The cone's volume is maximized when its height is two-thirds of the sphere's radius, which means the optimal height is ( \frac{2}{3} \times 12 \text{ cm} = 8 \text{ cm} ). Thus, the statement is incorrect; the correct height for maximum volume is 8 cm, not 16 cm.
What is the formula for dilution factor?
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
How many percent of the sun reach the earth surface?
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 .
What is formula to convert millimeter to cft?
A millimetre is a unit of distance. A cubic foot is a unit of volume. The two units are therefore incompatible.
