Answer:

center: (1, -3)
radius: 5

Step-by-step explanation:

Comparing the two given equations, we see ...

h = 1

k = -3

r = √25 = 5

The center is (1, -3), and the radius is 5.

What 1,045 to the nearest thousands

faltersainse [42]

1,045 to the nearest thousands would be <u>1,000</u> because you must round down since there are no numbers close enough to round up.

jenyasd209 [6]

<em>Answer:</em>

<em>≈ 24 cm</em>

<em>Step-by-step explanation:</em>

<em>Hi there !</em>

<em>c = 2πr } => c = πd => d = c/π</em>

<em>2r = d</em>

<em>replace c ; π</em>

<em>π =3.14</em>

<em>d = 74cm/3.14</em>

<em>= 23.5668</em>

<em>≈ 24 cm</em>
