Answer:
Therefore the measure of the central angle is 45.86°.
Step-by-step explanation:
Given:
Radius = 9 cm
arc length = 7.2 cm
pi = 3.14
To Find:
Central angle = θ =?
Solution:
If the θ measured in degree then the arc length is given as

Where r = radius, θ = Central angle
On substituting the values we get

Therefore the measure of the central angle is 45.86°.
Answer:
The answer is 60.48
Step-by-step explanation:
In order to find this, simply multiply the two terms together.
84% * 72
.84 * 72
60.48
You would divide the number twenty by four. So your answer would be five.
-0.5 / 0.021 = -23.8
0.4 / -0.4 = -1
Hope this helps:)
