How many square feet is a 18 foot circle?
Space and AstronomyHow many feet around is an 18 foot circle? The answer is 56.57 . What is the radius of a 18 circle? To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches. How do you find the sq ft of a circle?
Do stereoisomers have different physical properties?
Space and AstronomySTEREOISOMERS. Stereoisomers are isomeric molecules with the same chemical formula but a different atomic arrangement. As a consequence they possess similar chemical and physical properties. Do diastereomers have different physical properties? Diastereomers can have different physical properties and reactivity. They have different melting points and boiling points and different densities. They have two or more
How often do Moonbows occur?
Space and AstronomyThe moonbow typically appears for about five nights each month, starting from two to three nights before the full moon through two or three nights afterward – but only when the weather is clear. If it’s cloudy, there won’t be enough light. Are Moonbows rare? Lunar rainbows — moonbows — occur less than 10 percent
What is the function of the line diagram?
Space and AstronomyAs the name suggests, a one-line chart uses a single line to represent all three phases. This is the most basic type of electrical installation blueprint. A single line diagram shows the rating and capacity of electrical equipment and circuit conductors and protection devices. What a one-line diagram is and its functions? It shows a
What type of graph shows how the responding variable changes over time?
Space and AstronomyLine graphs are used to display data to show how one variable (the responding variable) changes in response to another variable (the manipulated variable). Why are line graphs powerful tools in science? They allow you to identify trends, make predictions, and recognize anomalous data. What graph shows how variables change over time? Line graphs are
What do you mean by minimum spanning tree?
Space and AstronomyThe Minimum Spanning Tree is the one whose cumulative edge weights have the smallest value, however. Think of it as the least cost path that goes through the entire graph and touches every vertex. What is meant by spanning tree? A spanning tree is a sub-graph of an undirected connected graph, which includes all the
What are the properties of the probability of an event?
Space and AstronomyProperties of Probability If there is no ambiguity in the occurrence of an event, then the probability of such an event is equal to 1. In other words, the probability of a certain event is 1. If an event has no chances of occurring, then its probability is 0. What are the three basic properties
Does a parallelogram have 4 90 degree angles?
Space and AstronomyRight Angles in Parallelograms Although students are taught that four-sided figures with right angles — 90 degrees — are either squares or rectangles, they are also parallelograms, but with four congruent angles instead of two pairs of two congruent angles. Do parallelograms have 4 90 angles? Solution: A Parallelogram can be defined as a quadrilateral
What are the properties of an isosceles triangle?
Space and AstronomyAn Isosceles Triangle has the following properties: Two sides are congruent to each other. The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle. The two angles opposite to the equal sides are congruent to each other. What are 3 properties of
What is the angle addition formula?
Space and AstronomyThe angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. What is the angle formula? What Is Formula for Finding Angles? Formula name Formula sin, cos, and tan sin θ = opposite / hypotenuse cos θ = adjacent / hypotenuse tan θ = opposite / adjacent Law
