Answer: 12.56 cm

Step-by-step explanation:

Pi looks like this <em>π or 3.14 or 22/7</em>

A formula for circumference is: <em>C = 2π r</em>

<em>The radius or r listed in the diagram is 2cm. </em>

1) Plug r into the equation...

<em>2) Simplify the equation</em>

<em>3) You can insert 4π to be exact in a calculator or do 4 x 3.14 (its still the same thing but you have to round if you are using this π)</em>

However both answers come out to be 12.56

Answer:

<em>As mean and median are equal, so the data will be in normal distribution in shape of a symmetrical "bell curve".</em>

Step-by-step explanation:

The given data: 10 5 8 10 12 6 8 10 15 6 12 18

<u>Mean is the simple average of all data</u>. As, there are total 12 data, so the Mean will be: $\frac{10+5+8+10+12+6+8+10+15+6+12+18}{12}= \frac{120}{12}=10$

For finding the Median, <u>first we need to rearrange the data according to the numerical order and then identify the middle value</u>. So........

5 6 6 8 8 10 10 10 12 12 15 18

Here the middle values are 10 and 10. So, the median will be the average of those two middle values.

Thus, Median $=\frac{10+10}{2}=\frac{20}{2}=10$

We can see that, <u>the relationship between the mean and the median is "they are equal"</u>. So, the data will be in normal distribution and the shape will be symmetrical "bell curve".

Answer:

Step-by-step explanation:

in interval ( 0 ; 2)

in interval (2; 4)

in interval (4 ; 6 )

The graph shows that at first the ball rises up ; and then it is seen that it goes down and loses height to zero , from which it can be concluded that the height after 10 seconds remains unchanged and therefore the height of the ball after 16 seconds will be zero

In ΔSTU, the measure of ∠U=90°, the measure of ∠T=32°, and US = 5.8 feet. Find the length of ST to the nearest tenth of a foot.

murzikaleks [220]

Answer:

10.9451≈10.9 feet

Step-by-step explanation:

sinT= hypotenuse/ opposite = x/5.8

sin32= x/5.8

x*sin 32=5.8

x=5.8/sin 32= <u>10.9451≈10.9 feet</u>
