# How to find central angle with radius and arc length

Central Angle of a Circle Calculator

Oct 05,  · A central angle is an angle with a vertex at the centre of a circle, whose arms extend to the circumference. You can imagine the central angle being at the tip of a pizza slice in a large circular pizza. You can find the central angle of a circle using the formula: ? = L / r. where ? is the central angle in radians, L is the arc length and r is the radius. arc length = [radius • central angle (radians)] arc length = circumference • [central angle (degrees) ? ] where circumference = [2 • ? • radius] Knowing two of these three variables, you can calculate the third. Even easier, this calculator can solve it for you. Do you want to solve for.

Calculating a circle's arc length, central angle, and circumference are not just tasks, but essential skills for geometry, trigonometry and beyond. The arc length is the measure of a given section of a circle's circumference; a central angle has a vertex at the center of cenral circle and the sides that pass through two points on the circle; and circumference is the distance around the circle. The vertex is the center of the circle. Calculating each of these is easy if you have the right tools and you're using the proper formulas.

Record the number on the protractor where the second side of the angle passes through the edge of the protractor. If the angle is larger than 90 degrees, record the top number; if the angle is smaller than 90 degrees, record the lower number.

This is the measurement of your central angle. Measure from a point on the circle to the central angle's vertex wity determine the radius of the circle. Calculate the central angle of your circle, using the protractor, then represent this angle as a fraction. As there are degrees in all circles, make the denominator of the fraction. The angle measurement is the numerator. Based in Halifax, Nova Scotia, Jordan Whitehouse has been writing on food and drink, small business, and community development since His work has appeared in a wide range of online and print publications across Canada, including Atlantic Business Magazine, The Grid and Halifax Magazine.

Whitehouse studied Brown sperm what does that mean literature and psychology at Queen's University, and book and magazine publishing at Centennial College. Place the base how to make money day trading of the protractor on one of the angle's sides. Multiply the radius by pi, a constant that is equal to approximately 3. Multiply the result by 2 to complete the ot calculation.

Divide the numerator by the denominator to place how to find central angle with radius and arc length number in decimal form. Multiply the circumference by the decimal to learn the arc length of that section of the circle. Things You'll Need. Copyright Leaf Group Ltd.

Calculating Circumference

How to calculate a central angle? First, determine the arc length. Measure or calculate the length of the arc. Next, determine the radius. You can find the central angle of a circle using the formula: ? = L / r. where ? is the central angle in radians, L is the arc length and r is the radius. Central angle when radius and length for major arc are given is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B provided the values for radius and length for the major arc is given and is represented as ? = L/r or central_angle = Length of Major Arc/Radius.
