What is density? How is density calculated? Give the formula for calculating density?Prepare a chart which will calculate the density of all 8planets of solar system. Use following steps to calculate density:i: Find a planet’s diameter in km. ii: Find the radius of the planet in km. iii: Convert kilometers to meters using a unit ratio.iv: Calculate the volume of a planet using the formula: volume = 4 π r3(Considering all the planets are spherical in shape)v: Lastly find the density of the planet.
pls be quick very imp

Answer:
density = mass/ volume and it is measured by a density bottle.
1. Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
2. The formula for density is d = M/V, where d is density, M is mass, and V is volume.
3. (In picture)
4. Planet diameter = 2p × (distance to the planet) × (planet's angular size in degrees)/360°. Planet volume = (p/6) × (planet diameter)3. Density = mass/volume.
5. The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA's Goddard Space Flight Center.
6. To calculate how many meters is 2 km, multiply 2 by 1000, that makes 2000m is 2 km.
7. Given formula for volume of a sphere is
V=

Formula for surface area of sphere is
A=4πr

Given is the surface area of a sphere = 36π
∴36π=4πr

∴r

=9
∴r=3
Putting r=3 in the formula of volume to find volume:
V=

∴V=4π(9)
∴V=36π
