Area of small circle = PI x r^2
r = 1/2 the diameter ( 1/2 * 3 = 1.5)
3.14 x 1.5^2 = 7.065 square cm
there are 2 small circles so total area for them = 7.065 * 2 = 14.13 square cm
the area for the large circle = PI x r^2
the radius of the large circle is 3 cm
3.14 x 3^2 = 28.26 square cm
the area of the shaded area is: 28.26 - 14.13 = 14.13 square cm, which can round down to 14 square cm.
Answer:
The tree is 14 ft. tall.
Step-by-step explanation:
If Ryan is 6 ft. tall and his shadow is 12 ft. tall than his shadow is twice his size. So if the trees shadow is 28 ft. tall then you would divide. Here is the equation:
28 ÷ 2 = 14
To check our work you would do 14 * 2 = 28.
Hope this helps!!
Answer:



Step-by-step explanation:
Mass of particles that a river can transport, 
where:
v = velocity of river flow
When 
then the mass transported, 
<u>When mass is twice:</u>
![v=\sqrt[6]{2}](https://tex.z-dn.net/?f=v%3D%5Csqrt%5B6%5D%7B2%7D)

<u>When mass is 10 times:</u>
![v=\sqrt[6]{10}](https://tex.z-dn.net/?f=v%3D%5Csqrt%5B6%5D%7B10%7D)

<u>When mass is 100 times:</u>
![v=\sqrt[6]{100}](https://tex.z-dn.net/?f=v%3D%5Csqrt%5B6%5D%7B100%7D)

Answer:
top box: ray
bottom box: endpoint
Step-by-step explanation:
top box: a ray is a line that doesn't stop and that is represented by a arrow on the end of it
bottom box: an end point is where a ray, or line segment stop and since i see two rays that stop there it is an endpoint
