3) The length of the longest chord of
the circle with radius 2.9 cm is
[1M]
O 3.5 cm
0 7 cm
O
10 cm
O 5.8 cm​

Answer 1

Answer:

5.8 is the right answer because radius of a circle is half then his diameter is double so longest chord of a circle is also a diameter....when we does doubled the radius of circle 2.9cm we get 5.9cm...

Answer 2

The diameter is the Longest chord of the Circle.

Therefore, Diameter of a circle = 2 × Radius of Circle

So, 2 × 2.9 cm = 5.8 cm

Hence, The length of the longest chord of the circle is 5.8 cm.
