\sf Hello!


\sf Formula\: to \:calculate \:length\: of\: an \:Arc :-


(\sf Φ)/(\sf 360) × \sf πr^(2)

Here,


\sf r = Radius

\sf Φ = \sf Angle\: subtended\: by\: radius\: at\: the\: Centre

Hi there!

When radius n' angle is provided.

Use following formula to calculate th' Length of th' Arc :-


(\theta)/(360) × 2πr

where,

• r = radius
• ϴ = angle subtended by radius at th' centre

~ Hope it helps
