How Do You Figure The Area Of A Cylinder? Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r) What is the area and volume of a cylinder? Things to Remember. Surface area of a cylinder = 2πr2 + 2πrh. Volume of a cylinder
Who Discovered Pi? The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. How did Archimedes find pi? Archimedes’ method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than
What Is Pi In Science? Pi is the ratio of circumference to diameter of a circle. … That’s why pi is important for scientists who work with planetary bodies and the spacecraft that visit them. What does pi stand for in science? In many countries, the term principal investigator (PI) refers to the holder of
What Is The Volume Of A 9 Cm Sphere? The volume of a sphere is equal to 43 times Pi π times the radius cubed. Substitute the value of the radius r=9 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14 . Combine 43 and π .
How Do You Find The Moment Of Inertia Of A Ring? The moment of inertia of a circular ring about an axis perpendicular to its plane passing through its centre is equal to MR2, where M is the mass of the ring and R is the radius of the ring. Hence, I=MR2. What is the
Which One Of The Following Has The Largest Atomic Radius? Na has the largest atomic radius. Reason: Li : belongs to the 2nd period. Na and Cl : belong to the 3rd period. Which element has the largest atomic radius sodium or aluminum? Sodium has fewer electrons than aluminum and therefore a weaker inward pull
Why Does Group 1 Have The Largest Atomic Radius? Element lithium Atomic Number (Z) 3 Symbol Li Simple Electron Configuration 2,1 Why do alkali metals have the largest radius? Alkali metals have largest covalent radii because they poses only 1 electron in their outer level and good screening in inner level and that results lower
Why Is Centripetal Acceleration Not Affected By Mass? Where is the centripetal acceleration on an object, is the velocity of an object, and is the radius in which the object moves in a circle. We can see that mass does not play a role in the centripetal acceleration of an object, so no matter what
What Is The Shape Of Saturn? Saturn is a gas giant composed predominantly of hydrogen and helium. It lacks a definite surface, though it may have a solid core. Saturn’s rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator. What
What Determines Atomic Radius? Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group. What factors affect atomic radius? Factors Affecting
