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

Answer:

P = 53.6 square cm

Step-by-step 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°$=\frac{\pi }{2}$.

Substituing the given values to get:

$P=\frac{\pi}{2}(15)+2\times 15$

P = 53.6 square cm
