The formula is used to find the diameter of circle is: d = \frac{C}{3.14}

The diameter of circle is 5.1 cm

<em><u>Solution:</u></em>

Given that,

Circumference (C) of a circle is 16 cm

<em><u>The formula for circumference of circle when diameter is given is:</u></em>

C = \pi d\\\\\pi \text{ is a constant equal to 3.14}\\\\C = 3.14d

<em><u>Rearrange the formula to get "d"</u></em>

Divide both sides by 3.14

d = \frac{C}{3.14}

The above formula is used to find the diameter of circle

Given that, circumeference = C = 16 cm

Substituting we get,

d = \frac{16}{3.14}\\\\d = 5.095 \approx 5.1

Thus diameter of circle is 5.1 cm

Answer:

a. True

Step-by-step explanation:

By ∝= 5% we mean that there are about 5 chances in 100 of incorrectly rejecting a true null hypothesis. To put it in another way , we say that we are 95% confident in making the correct decision.

In the given question the null hypothesis is

H0: u ≤ 1 hour and Ha:  u > 1 hour

So there is a 5% chance that the erroneous conclusion will be made that students spend on average more than 1 hour per assignment.

The given statement is true.

Answer:

Percent error is approx. 22%

Step-by-step explanation:

So to do this you need to know the formula for percent error, which is

percent error = l measured - theoretical / theoretical l * 100%

With this just plug in 18 (real) and 14 (measured).

percent error = l 14 - 18 / 18 l * 100%

percent error = l -4 / 18 l *100%

percent error = l -2/9 l *100%

You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.
