The answer is 126$ Just divide 127 divided by 22 then multiply that by 21
- Center =
![(h,k) = (0,2.25)](https://tex.z-dn.net/?f=%28h%2Ck%29%20%3D%20%280%2C2.25%29)
- Radius =
![r = \frac{14}{13}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B14%7D%7B13%7D)
<u>Step-by-step explanation:</u>
Here we have following equation : ![x^{2}+(y-2.25)^{2} = \dfrac{196}{169}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B%28y-2.25%29%5E%7B2%7D%20%3D%20%5Cdfrac%7B196%7D%7B169%7D)
We need to find the center & radius of this circle . Let's find out:
We know that , Equation of a circle is given by :
⇒
........(1)
Here , (h,k) are the co-ordinates of center & r is the radius of circle.Collectively called as a circle with radius r and center at (h,k) . Let's frame given equation in question :
⇒ ![x^{2}+(y-2.25)^{2} = \frac{196}{169}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B%28y-2.25%29%5E%7B2%7D%20%3D%20%5Cfrac%7B196%7D%7B169%7D)
⇒ ![(x-0)^{2}+(y-2.25)^{2} = (\frac{14}{13})^2](https://tex.z-dn.net/?f=%28x-0%29%5E%7B2%7D%2B%28y-2.25%29%5E%7B2%7D%20%3D%20%28%5Cfrac%7B14%7D%7B13%7D%29%5E2)
On comparing this equation with equation (1) we get :
- Center =
![(h,k) = (0,2.25)](https://tex.z-dn.net/?f=%28h%2Ck%29%20%3D%20%280%2C2.25%29)
- Radius =
![r = \frac{14}{13}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B14%7D%7B13%7D)
Volcanic eruptions release molten rock or lava that can form new rock on the earth's surface. The gases,dust, and ashes that erupt from a volcano also affect the climate by covering the earth's surface; therefore, creating a cooling effect on the location of the volcano. Also, in the past where there were super volcanic eruptions that it caused global warming due to volcanoes also releasing greenhouse gases.
