Question

What is the arc length if the radius of the circle is 15 and the angle og the sector id 90 degrees

Answer 1

P = 53.6 square cm

Explanation:

We know that the measure of an arc of a sector is given by:
`P=\theta r+2r`

Where
`\theta` is the angle of the arc of the sector (radian) while
`r` is the radius of the circle.

Here,
`\theta =` 90°
`=(\pi )/(2)`.

Substituing the given values to get:

`P=(\pi)/(2)(15)+2* 15`

P = 53.6 square cm
