Firstly let's find hypotenuse(let it will be "n" of smaller triangle
Let use Pythagorean theorem

Now we need to find hypotenuse(x) of bigger triangle

The value of x must be rounded to 1 DP, so

Answer: x=24.1
18,430! I hope this helps you out!
Step-by-step explanation:
I haven't used distance formula or Pythagoras theorem, not sure why that's given at the bottom of your question. check the image. that is how I solved it
Answer:
We know length of one quarter of a circle = 2πr/4 = πr/2
So here we can make the equation for to find thr value of radius r
length of one quarter given = 25 cm
so πr/2 = 25 cm
=> πr = 50 cm
=> r = 50/π cm
So the entire circumference of circle =
2πr
= 2 π 50/π cm
= 100π/π cm (ans)
Here we dont substitute the value of π due to represent the answer in terms of pi.
Hope it helps you
It will go in it 9 times cause 9*20=180
