Question

When give you an angle in degree and the radius, how do you calculate the arc length?

Answer 1

$\sf Hello!$

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

$\dfrac{\sf Φ}{\sf 360} × \sf πr^{2}$

Here,

• $\sf r = Radius$
• $\sf Φ = \sf Angle\: subtended\: by\: radius\: at\: the\: Centre$

Answer 2

Hi there!

When radius n' angle is provided.

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

$\dfrac{\theta}{360}$ × 2πr

where,

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

~ Hope it helps
