Answer:

The radius is: 1

Step-by-step explanation:

The equation of a circle in center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is at the point (h, k) and the radius is "r".

Given the equation of the circle:

x^2+y^2=1

You can identify that:

r^2=1

Then, solving for "r", you get that the radius of the circle is:

r=\sqrt{1}\\\\r=1

Answer:

Radius = 1

Step-by-step explanation:

It is given that equation of a circle is x² + y² = 1

<u>Points to remember</u>

Equation of a circle with center(h, k) and radius r is given by,

(x - h)²  + (y - k)² = r²

<u>To find the radius of circle</u>

Compare the two equations

x² + y² = 1  and (x - h)²  + (y - k)² = r²

we get the center is (0, 0)

therefore we can write

r² = 1

r = 1

Therefore radius r = 1

anastassius [24]

All three are similar

In ∆SUT and ∆VWX

  • Two sides are similar and one angle is similar

So by SSA they are similar

In ∆PRQ and rest two

All angles are.

  • 80,80,20°

So

They are similar by AAA congruence
