How to prove points belong to the same circle

1 answer:

4 0

Not sure what the mess above me says, but basically as long as you have an equation for the circle, you can plug the coordinates of your point into the x and y values of the equation and see if it equals out. If you don’t have an equation, you can just make one. Use (f-k)^2+(x-h)^2=r^2 where h and k are the coordinates of the center of the circle and r is the radius. Hope this helps!

$\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}$

$\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}$

$\text {Difference = }5.97 \times 10^{24} - 4.87 \times 10^{24}$

$\text {Difference = }(5.97 - 4.87) \times 10^{24}$

$\text {Difference = }1.1 \times 10^{24} \text { kg}$

--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24}
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg
