A radian is a unit of measurement commonly used in mathematics and physics to measure angles. It is defined as the angle subtended by an arc of a circle that has the same length as the circle's radius. How do you convert degrees to radians?
Calculate the length of the arc. Now that we know the radius, we can easily find the length of the arc. If the angle of the arc is given in radians we use the formula: s= ?r If the angle of the arc is given in degrees we use the formula: s= (?/360) x 2 ?r Step 4 Try...

For the circle with radius s, the circumference is equal to 2 * π * s. The arc length of the sector is equal to 2 * π * r. The area of a sector –which is our lateral surface of a cone – is given by the formula: A(lateral) = (s * (arc length)) / 2 = (s * 2 ...
Calculate angle D if the holes are evenly spaced around the circle. Evaluate R ( x 2 + y 2 + 5 ) d A where R is the circle of radius 4 centered at the origin. Evaluate ydx-xdy given C is the circle with radius ...
Trigonometry is largely based on the Pythagorean Theorem which is used to calculate the length of sides of a triangle. The hypotenuse (H) is the longest side of the triangle opposite to the 90 degree angle. The other two sides are known as the base (B) and perpendicular (P) side. The...
