Answer:

The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m

The equation would be:

144 x 3.14 - 64 x 3.14 = 251.2

Step-by-step explanation:

First, you need to find out what the whole circle is:

The whole circle is 452.16

Then, find the inner circle :

8 x 8 x 3.14

200.96

Last, subtract the whole by the inner:

452.16 - 200.96 = 251.2

hope this helps!

If the foreign exchange rate between the U.S. dollar and the Danish krone is 1:2.50, how many Danish kroner will you get for $5?

enyata [817]

$\bf \begin{array}{ccll} US~\$&Danish~\$\\ \cline{1-2} 1&2.50\\ 5&d \end{array}\implies \cfrac{1}{5}=\cfrac{2.50}{d}\implies d=\cfrac{5\cdot 2.50}{1}\implies d=12.5$

A cone has a radius of 7 cm and a height of 12 cm what is the volume in cubic meters of the cone

tigry1 [53]

Answer: 615.44 m^3.

Step-by-step explanation: To find the volume of a cone, you need to multiply the radius, pi, and height. The equation is given below:

π x r^2 x h = V, where π is pi, r is the radius squared, h is the height, and V is the volume.

Now, we need to substitute the values with the information that is given. π ≈ 3.14:

3.14 x 7^2 x 12 ≈ 1846.32.

We are not finished yet! A cone's volume is a third of a cylinder's, so you need to split 1846.32 in 1/3:

1/3 x 1846.32 ≈ 615.44 m^3.

Hope this helps! :)
