3) If the diameter of a circle is 6cm, What will it's radius be?
4) Identify the types of angle.
0.2)B) Attempt the followings. (Any-2)
1) Draw and name the following angles with the help of a
protractor. -) 165
L) 45
2) Draw circles with the radii given below and show centre, radius
& diameter 20
3) Write the names of the points in the interior & exterior of the
circle​

Answer 1

Answer:

Radius of circle =16cm

Length of perpendicular to chord from center =16−3=13cm

Perpendicular from center to any chord bisects the chord.

So, by Pythagoras' theorem, the half length of the chord is =

16

2

−13

2

=

87

So the length of the chord is =2

87

cm

So option C is the right answer.
