Question

the semi circles are drawn outside a triangle so that the sides of the triangle are the diameters of the semi circles. if the triangle is a right angled triangle and theses semi circles have areas 18, 32, and 50 determine the area of the triangle? @Mathematics

Answer 1

1. Set A = (pir^2)/2
2. Find the radius
3. Multiply the radius by 2 to find the diameter
4. Repeat for the other two sides of the triangle
5. Verify that the sides satisfy pythagorean theorem
6. Use Heron's formula to find area of triangle

Answer 2

can you show me how?

Answer 3

Yes. If you have skype, it's easier. If not there are other means.

Answer 4

I only mention skype because it has a screen sharing function

Answer 5

Showing you on here would take forever

Answer 6

i dont have one

Answer 7

I wish you did

Answer 8

show me the first step only

Answer 9

Oops, you have to divide it by 2 before sqrt rooting it

Answer 10

wait...

Answer 11

A = (pir^2)/2
18 = (pir^2)/2
36 = pir^2
36/pi = r^2
sqrt{36/pi} = r

Answer 12

So one of the sides of the triangle is 3.385

Answer 13

i hope that makes sense

Answer 14

not Really

Answer 15

If you want to understand it, you must get skype because I can explain it to you as well as show you step by step how to do it. You will only need audio and chat. You don't even need a microphone to use skype and it is free to download and install. If you really want to understand this, you can get it and save yourself from all kinds of trouble. If you don't like it, you can just uninstall it.
