1/4 exact form, 0.25 decimal form.
81/5 = 16.2
8.5
84/5 = 16.8
8.44
So from least to greatest would be: 8.44, 8.5, 16.2, 16.8
Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!
The measure of the central angle of a circle is 45⁰
<h3>What is Angle?</h3>
A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
Here,
Theta (angle) θ = arc length / radius
θ = 15 π / 60 cm
θ = 0.79 radians
Convert to degrees
θ = 0.79 radians = 0.79 X 180/ π
= 0.79 X 180/ 3.14
= 45⁰
Thus, the measure of the central angle of a circle is 45⁰.
