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.
Homework Statement
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...
Homework Statement
