In my solution, first circle is 10 then the second is 5. after that, I used s = a/(1-r). a=25 since 5 will be squared and r=1/4. So my solution is A = pi[10^2 + 5^2 +25/(1-1/4). so my answer becomes 475/3 pi.
Please see the attached figure
The radius of the biggest circle is 10.
The required is the sum of all circles and the sum of all triangles in the figure.
There is an infinite number of circles and triangles.
My answers are:
for circle: 475/3 pi
for triangle: 175/2...
how can i find the length of an oblique triangle given the 3 altitudes (the line drawn perpendicular from a point of the triangle to the opposite side).
I have no idea on how to solve it.
