I am not sure but I think the answer is of second one.
We are given a circle with center O.
We can see that we have a radius OB of given circle.
OC and OE are another two radii.
EC is a diameter of the circle.
<em>Diameter is the segment that cut the circle at two points and passes through center.</em>
AB is a tangent of the given circle.
<em>A tangent is a segment that cut a circle at one point only.</em>
But the chord is GD.
<em>A chord of a circle is the segment that cut a circle at two points.</em>
<h3>Therefore, a chord in circle O is GD.</h3><h3 />
It will be 4.4 when rounded up.
Answer:6000
Locate and underline the tens place 0 then look at the digit to the right 0,:The digit to the right 0 is 4 or below. So, you replace it by a 0 zero to get 6000 as the answer.
