How did Galileo discovered that the earth is a sphere?
Galileo did not discover that the Earth is a sphere; this fact was already known by ancient Greek astronomers. However, Galileo's observations through his telescope, including the phases of Venus and the moons of Jupiter, provided further evidence to support the heliocentric model of the solar system proposed by Copernicus, which implied that Earth was also a sphere.
Why are there two different formulas for calculating a cylinder and a sphere?
Cylinders and spheres are different geometric shapes with different properties. The formulas for calculating their volume and surface area reflect these differences in shape and dimensions. The formula for a cylinder involves multiplying the base area by the height, while the formula for a sphere involves powers of the radius to account for its spherical shape.
How to find cubic feet in a sphere?
To find the cubic feet in a sphere, use the formula for the volume of a sphere which is (4/3)πr^3, where r is the radius of the sphere. Once you calculate the volume in cubic units, convert it to cubic feet by considering that 1 cubic foot is equal to 27 cubic feet.
When was neopentane discovered?
Neopentane was first discovered by Stanley M. Byrn in 1910. It is a branched-chain hydrocarbon with the molecular formula C5H12.
Any formula for volume uses perpendicular measures.?
Not necessarily. The volume of a sphere is 4/3*pi*r^3.
