    Circle Sector Calculator

    getcalc.com's circle sector calculator is an online basic geometry tool to calculate area of sector & length of an arc (partial circumference length), in both US customary & metric (SI) units.

    Steps to Find Area & Length of a Circle Sector

    The step by step workout for how to find what is area & length of a circle sector. Students may use this circle sector calculator to generate work with steps for any other similar input values.Workout :
    step 1 Address the formula, input parameter and values
    Radius = 5 in
    Angle = 45 °

    step 2 Find Area of Circle Sector using Radius and Angle values
    Area A = πr²θ/360
    = π x (5)² x 45/360in²
    = 22 x 25 x 45/(7 x 360)in²
    = 24750/2520in²
    Area A = 9.8214 in²

    step 3 Find Length of Circle Sector using radius and angle values
    Length L = 2πrθ/360in
    = 2 x 22 x 5 x 45/(7 x 360)in
    = 9900/2520in
    Length L = 3.9286 in

    Circle Sector & Formulas

    Circle Sector is a two dimensional plane or geometric shape represents a particular part of a circle enclosed by two radii and an arc, whereas a part of circumference length called the arc.
