circles

Hello all! I would really appreciate it if you helped me with this problem. It's for my Geometry Honors class and it's quite overwhelming. It is about circles and determining inscribed angles, central angles, and other angles. Here is the problem (diagram and given information)...

(type, title should say 'outer, not out') OK, I need help with this :) Trying to find the percentage increase of the outer overall circumerference of 2 ajoined circles when each circle increases it's diameter by a fixed known percentage. Here is a drawing, hopefully you'll see what I'm...

Hi guys, first time poster here! There' this equation I don't quite understand. I'm given the following question: The tangent line to the curve (x^2) (y^2) − (2x^2) + (y^2) = 0 at the point (1, 1) is=? Not quite sure how to deal with the circle arranged that way? I really need to understand...

Hello! I have an interesting task i am trying to solve. Given are two circles with centers. A segment a is given too. We have to find all parallel segments to a with same length as a, such that on end of these segments lies on Circle 1 and the other end lies on Circle 2. Kind of tricky for...

Hi I have an equation dr/dt = 1/5R(2-R); R(0) = 0.5 I can see it is in terms of R and t however need to solve exactly for R(t)..Do I: Re-arrange so all R's together: 1/dt = (1/5R(2-R))dr then integrate both sides. If yes I can't automatically see how to integrate RHS, any pointers would be...

Hi everyone :) I have learnt the general equation for circles and know how to figure out questions when the centre point is given along with any other point in the circle, however the following question doesn't give specific points as to where the centre is and I'm unsure of how to figure it...

Hi; Let T be a standard torus in R^3. Let C_1 and C_2 be two circles in T such that C_1 and C_2 intersect transversally at two distinct points, say p and q. By transverse intersection I mean tangent intersection is not allowed. Orient C_1 and C_2 and let l_1 be an arc in C_1 from p to q...

(sorry, I don't know in which section I should post this question) I now think I have some idea why Cantor (or whoever it is) said things like "there are more real numbers R than whole numbers N." So I think I've understood the concept of comparing infinite sets. And why this is...

Representing one unit by at least five squares on your graph paper, draw the unit circle, which is centered at the origin and goes through point A = (1, 0). Use a protractor to mark the third-quadrant point P on the circle for which arc AP has angular size 215º. Estimate the coordinates ofP...

Not sure how to find angle AOC. I know ACB is 90 and ABC is 90-(theta) but still stuck [emoji53]

Hi so my question is how do i find the area of the smaller circles if i don't have the radius of the smaller circles but only the large one? here is the question context "The cross section of a large circular conduit with radius 12.00 cm has seven smaller equal circular conduits within it." a)...

Hi, im new here. have one question to ask regarding maths questions related to circles topic. Please help the question is attached here. answer given in the book is 208 2/7 cm square There are two languages there. One is Malay another is English. You may just look at the italic words which...

I have Circles 1 & 2 which are are at a fixed size and location. I have a line segment A-B that is a fixed length and bearing. I need to place the line segment so that its endpoints touch both circles. How would I go about finding out the location for A-B?

Can someone explain what i need to do to solve these problems? I tried solving #13 with 9x+4=1/2(11x+x^2) but something went wrong. I might be using the wrong equation. Any help would be appreciated!!

can someone help me solve this problem? I have to find the value of x. It says assume the segments are tangents if they appear to be.. thanks in advance!

How do I find using differentiation the conmen tangent between two circles x2 +y2= 16 and (x-6)2+y2​= 4

Dear all; Can you help me to find the fundamental group of two circles joined by an arc. In other word, let S_1 and S_2 be two standard circles. Let p_1 and p_2 be two points in S_1 and S_2 respectively. Join p_1 and p_2 by an arc l. Let S be union of S_1,S_2 and l. What is the fundamental...

three circles touch each other, the centres of the circles form a 3 4 5 triangle, how big is the big circle?
