Answer:
x = 61.3°
Step-by-step explanation:
We are given the radius r = 9 cm and arc length l = 9.7 cm. We need to find the angle x in degrees.
The formula used is:
l = rФ
In our case Ф = x. So re writing the formula:
l= rx
9.7 = 9 x
=> x = 9.7 / 9
x = 1.07 radians
Converting radians into degree we need to multiply the value of x by
180/π where π = 3.14
x = 1.07 * 180/3.14
x = 61.3°
