65 (number)

In geometry, a circular segment (symbol: ⌓) is an area of a circle informally defined as an area which is "cut off" from the rest of the circle by a secant or a chord.

Formulas

A circular segment (in green) is enclosed between a secant/chord (the dashed line) and the arc whose endpoints equal the chord's (the arc shown above the green area).

Let R be the radius of the circle, θ is the central angle in radians, α is the central angle in degrees, c the chord length, s the arc length, h the height of the segment, and d the height of the triangular portion.

• The radius is $R=h+d=h/2+c^{2}/8h{\frac {}{}}$
• The arc length is $s={\frac {\alpha }{180}}\pi R={\theta }R$

• The chord length is $c=2R\sin {\frac {\theta }{2}}=R{\sqrt {2-2\cos \theta }}$

• The height is $h=R(1-\cos {\frac {\theta }{2}})=R-{\sqrt {R^{2}-{\frac {c^{2}}{4}}}}$

• The angle is $\theta =2\arccos {\frac {d}{R}}=2\arcsin {\frac {c}{2R}}$

Area

The area of the circular segment is equal to the area of the circular sector minus the area of the triangular portion.

Area of Segment = ½ × (θ - sin θ) × R² (when angle is in radians)

Area of Segment = ½ × ( (α × π/180) - sin α) × R² (when angle is in degrees)

After that you can get Hostgator to host your domain and use the wordpress to do the blogging. Once you start site flipping, trust me you will not be able to stop. I cut my webmaster teeth on Control Panel many years ago, but since had left for other hosting companies with more commercial (cough, cough) interfaces. If you don't like it, you can chalk it up to experience and go on. First, find a good starter template design. When I signed up, I did a search for current "HostGator codes" on the web, which enabled me to receive a one-word entry for a discount.
