The above expression is also an area of a sector formula, but this time the central angle is measured in radians. Example 1: Area of a Sector of a Circle Using Degrees What is the area of a circular sector whose radius is {eq}3 {/eq} cm and the central angle is {eq}4 5^{\cir...
A circle can be defined as, it is the locus of all points equidistant from a central point. In this we discuss about Properties of circle, circle formulas
For angles of 2π (full circle), the area is equal to πr²: 2π →πr² So, what's the area for the sector of a circle: α→ Sector Area From the proportion, we can easily find the final sector area formula: Sector Area = α×πr² / 2π = α× r² / 2 The sa...
The formula for the area of a circle is πr2; where r denotes the radius of the circle. To find the area of a sector of the circle, we simply multiply the θ360∘ by the area of the circle. It can be written as follows: ...
The formula to find the area of a sector of a circle is given by: A = (θ/360) x πr^2 where A is the area of the sector, θ is the central angle of the sector in degrees, r is the radius of the circle, and π (pi) is a mathematical constant that is approximately equal ...
What is the formula for arc length of a sector? The formula to find the arc length of a sector is as follows: s=rθ, where you would need the length of the radius between the endpoint of the arc and the center of the circle, and the angle's measure in radians. How do you find...
Calculate The Area Of A Sector (Using Formula In Degrees) We can calculate the area of the sector, given the central angle and radius of circle. Example: Given that the radius of the circle is 5 cm, calculate the area of the shaded sector. (Take π = 3.142). ...
