The formula for the volume of a sphere?
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
How do engineers get the total mass when designing a ship?
getting the formula of MA mass x acceleration
What is the formula to calculate weight?
Weight=m*g m=mass g=acceleration of gravity
How do you calculate concentration factor in chemistry?
You need to know density and percent by weight. Then use the following formula: ((1000)density x % by weight) / formula mass=concentration
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 .
