WebMar 10, 2024 · The easiest formula to calculate the perimeter of a triangleis – as usual – by summing all sides: Ptriangle=a+b+cP_{\mathrm{triangle}} = a+b+cPtriangle =a+b+c However, you aren't always given three sides. What can you do then? Well, instead of fretting, you can use the law of cosines calculatorto find the missing side: WebArea of sector = θ 360 ∘ × π r 2. If is measured in radians, then “the area of a sector of a circle formula” is given by. Area of sector = 1 2 × θ × r 2. Perimeter of sector = 2 r + θ 360 × 2 π r.
