Answer:
There are a total of 360° in any given circle, so an arc swept out by 60° of that 360° would make up 60/360 = 1/6 of the circle's circumference.
The formal for the circumference of a circle comes out of the definition of one of the most famous constants in mathematics: π. π is defined as the ratio between a circle's circumference and its diameter, or:
From this definition, we can multiply both sides of the equation by d to obtain
or, circumference is π times the diameter. To find the diameter, we just need to double the radius, giving us 5 * 2 = 10cm. Usually you'll see π approximated as 3.14, which is likely what they want you to use here. Using that approximation, we find the circumference to be 3.14 * 10 = 31.4 cm.
Finally, to get the length of that arc, we just need to take 1/6 of the circumference (since the arc sweeps out 1/6 of the circle), giving us 31.4 * 1/6 ≈ 5.2 cm.
Step-by-step explanation:
In order to have a great experiment and great data for analyzing you must have the best experiment design possible.Experiment design is the process of organizing the experiment properly to ensure that the right type and amount of data are available to answer the questions of interest. Some of the tips to follow in order to have good experimental design are:
-Choose a topic that will interest and challenge you.<span>Do not pick a broad topic.
</span>- Spend a lot of time gathering background research.
<span>- Predict the outcome of your experiment with the help of equation.
</span>-Keep a detailed and up-to-date lab notebook with the results.
<span>- Do as many trials as possible .
</span><span>- During the experiment, do not get discouraged if you run into a lot of problems..</span>
