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` :-


`(\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 :-


`(\theta)/(360)` × 2πr

where,

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

~ Hope it helps
