The radius of a circle, half of its diameter, can help you find the circumference in a couple of steps. First, double the radius to get the diameter (radius x 2, or radius + radius). One you have the diameter, you can use the equation C = πd. If you want to know the circumfe...
Find the eccentricity of an ellipse. This is given as e = (1-b^2/a^2)^(1/2). Note that an ellipse with major and minor axes of equal length has an eccentricity of 0 and is therefore a circle. Since a is the length of the semi-major axis, a >= b and therefore 0 <= e <...
Draw a circle on a piece of paper using a compass. Pull the legs of the compass apart until the space between them measures one-half of the desired diameter of your circle. Place the needle of the compass down on the spot that will be the circle's center point. Put down the leg wit...
She has 20 years of experience teaching collegiate mathematics at various institutions.Cite this lesson In geometry, an ellipse is a normal oval shape. Learn how to find the minor and major axes of an ellipse, review the definition of an ellipse, and solve problems to gain understanding. ...
Find the eccentricity of an elliptical orbit with one focus, earth's center, E. What angular resolution would you need to see the Sun and Earth as distinct points of light? If you were looking at it from 13 light years away? An AU (Astronomical Unit) is the...
It's a rather full-circle moment for the siblings as well. As they lean into the music their dad played growing up, they're all dads themselves (ironically, to all girls). As the bros point out, it's also the first time they've all been in the same place in...

Simon Sinek is a motivational speaker and organizational consultant. In his popular Ted Talk, “How great leaders inspire action”, Sinek talks about what he calls the “golden circle.” It explores, the what, how, and why of storytelling. ...
a=b=6,378,137.0 meters c=6,356,752.3142 meters Applying geometric methods yields the formula for the radius of the circle of latitude: Rlat=a*cos(lat)/(1-e2sin2(lat))1/2 where: e2 (eccentricity) = (a2-c2)/a2 = 0.00669438; Fig 1) Sidereal time vs. solar time. Left (solar ...
The position and shape of Vega's debris disk are intriguing simply for how unique they are. For comparison, Fomalhaut, a star very similar to Vega, also has a debris disk, but it has a much higher eccentricity that ranges from 0.12 to 0.31. Due to this higher eccentricity, Fomalhaut's ...
