Notice the angle formed by the two radii. Divide this angle by 360 to find out what portion of the circle it represents. For instance, if the angle is 45 degrees, divide 45 by 360 to get 0.125. Step 2 Find the area of the circle by squaring the radius and multiplying that by 3.14 ...
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...
Suppose F(x,y) = (2x-2y) i + 5x j and C is the counter clockwise oriented sector of a circle centered at the origin with radius 5 and central angle \pi/3 . Use Green's theorem to calculate the l Calculate \oint...
and then calculate a distance that is equal to the length of the straight segment, plus the arc radius, plus half the polyline's width, and use a perpendicular vector from that point on the first vector/line segment, having a length equal to the arc segment's radius plus half the polyli...
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...
Circle is a two dimensional figure which is taught in geometry. Circle is the locus of all the points at fixed distance (say it as r) from a given point (say it as C) Answer and Explanation:1 Angle subtended by an arc at the center is double the angle subtended by the arc at any...
