Jul 30, 2024 · The formula to calculate the area of a circle using radius is as follows: Area of a circle = π × r 2. And, to calculate the area of a circle using diameter use the following equation: Area of a circle = π × (d/2) 2. where: π is approximately equal to 3.14. It doesn't matter whether you want to find the area of a circle using diameter or ...
Radian. A unit of angle measure. based on arc length. In a circle of radius r, if a central angle has a measure of 1 radian, then the length of the intercepted arc is r units. 2π radians = 360°. 1 radian ≈ 57°. . Degrees to radians conversion. m°/360 ⋅ 2π.

This article is about the Arc Length Calculator. It explains how to calculate the length of an arc and the area of a circle sector using formulas and provides step-by-step instructions on how to find these values. The article also covers calculating arc length without radius by finding central angle or circle's radius first.
This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. The article explains the formula in detail and provides step-by-step instructions on how to find the arc length.
The length depends on radius and central angle, it is equal to radius multiplied by central angle (in radians).
Find area by multiplying πr² with r² * θ / 2.
Apr 7, 2020 · Since ∠AKB and ∠AKC are supplementary, they have a sum of 180 degrees. You can find the measure of ∠AKB as follows: θ = ∠AKB = 180 - 117 = 63 degrees. So θ = 63 and r = 5. Now that you know the value of θ and r, you can substitute those values into the Sector Area Formula and solve as follows: Replace θ with 63. Replace r with 5.
