Question

find the radios of a circle in which a central angle of 45° intercepts an arc of length 33 cm

Answer 1

$33 = 2(22/7) r</p> <p>r = 5.25 cm$Given that arc length of a circle = 33 cm.

Central angle = 45 degrees

To find the radius of the circle:

Recall the formula for arc length s

s = $\frac{x}{360} (2\pi r)$

Here s = 33 cm.  π=22/7

Substitute all these values in the formula:
