Find the areas of the circle, if diameter=16cm

Mathematics

Reika [66]3 years ago

Hey there!


Formula for the area of a circle: A = \pi r^2

Formula for the radius of a circle: r = d/2\\


First, let's divide the diameter by 2 in order to find the radius.

16/2 = 8

Next, we'll plug our values into the formula (found above).

A = pi x 8^2

A = pi x 64

A = 64pi^2 or A = 201.1cm^2


Hope this helps!! :)

Answer:

The function that best models the given data is;

B. h(t) = -6.73·t² + 14.19·t + 0.83

Step-by-step explanation:

The data in the given table is presented as follows

\begin{array}{cccccc}Time, \, t(s)&0&0.5& 1.0 & 1.5& 2.0\\Height, \, h \, (m) & 1.0 & 5.42 & 9.71 & 5.9 & 2.6\end{array}

Where;

Time, t(s) is the independent variable

Height, h(m) is the dependent variable

Therefore, we have;

When t = 0, h = 1.0

From the given functions, we have the following table of the result of the function generated with Microsoft Excel

\begin{array}{cccccc}\\t & h & A & B & C& D\\0 & 1.0 & 1.22 & 0.83& 0.83& 1.22\\0.5 & 5.42 & 5.26 & 6.2425 & 9.6075 & 10.17\\1 & 9.71 &  4.39 & 8.79 & 21.75 & 24.03 \\ 1.5 & 5.9 &  -1.39& 6.9725& 37.2575 &42.8\\2& 2.6 & -12.08 & 2.29 & 56.13 & 66.48\end{array}

By comparison, the function that nest models the given data is the function 'B', given as follows;

h(t) = -6.73·t² + 14.19·t + 0.83.

Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter. How long is the re
vekshin1

Answer:

\frac{7}{10}

Step-by-step explanation:

Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter

Lets add all the cut of pieces and subtract it from 2 meters

\frac{5}{10} +\frac{1}{10}+\frac{7}{10}=\frac{13}{10}

Now we subtract 13/10 from 2 meters

2 - \frac{13}{10}

To subtract , make the denominator same

\frac{2*10}{1*10} - \frac{13}{10}=\frac{20}{10} - \frac{13}{10}=\frac{7}{10}

7/10 meter is the remaining piece of ribbon
