The equation of a circle is (x−2)^2+(y−16)^2=169 . What is the circle's radius?

1 answer:

8 0

Hello!

The equation for a circle is

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

r is the radius

To find the radius we take the square root of the number in the radius spot

sqrt169 = 13

The answer is 13

Hope this helps!

Answer:

this is the answer for (03.01 LC)

$\sqrt{50}$

Step-by-step explanation:

You have use the Pythagorean Theorem a^{2} + b^{2} = c^{2}

So this is my work

$x^{5} + x^{5} = c^{2} \\25 + 25 = c^{2} \\50= c^{2} \\\sqrt{50} = \sqrt{c^{2} } \\\sqrt{50} = c\\$

extra notes

If you didn't know, you cancel exponents with roots.

So the c^{2} is cancled by aka \sqrt{c}

You can't simplify $\sqrt{50}$ so it stays like that

Answer: the answer for (03.06 LC)

Step-by-step explanation:

In pic

Just look for r after substituting the variables
