Answer:
12
Step-by-step explanation:
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 />
Answer:
283.6429m^2
Step-by-step explanation:
Area of a circle=πr^2
The radius is diameter divided by 2
Thus 9.5m
Therefore;
22/7×(9.5)^2
22/7×90.25
283.6429m^2 ANSWER
Power = Work done / time
Work done = Force * Distance
= 300 N * 1.5 m = 450 J
<span>Power = 450 / 0.75 = 600 Watts.</span>
