Hey buddy, I unfortunately can't send you the pic of the answer. but I can surely tell you how to do it. with explanation of how to draw it.
Ans:RADIUS of a) 3 cm b) 4 cm c) 4.2 cm d) 2.7 cm.
Explanation: (I will tell how to do the first part, do the other parts with the same method) Take a geometrical compass and take a pencil and a scale. Measure 3 cm on the scale and open the compass that much wide such that the metal tip of the compass should touch 0 on the scale and the pencil tip of the compass should touch 3 cm on the scale. Then, without changing the wideness of the compass, place it on a paper and draw a circle. And there you have it. Now let me make you understand. Radius of the circle is half of the diameter. for example, If diameter is x, then radius will be x/2 that is x÷ 2. So, if you take the radius of the circle and draw the circle using the radius, then the left side of the circle is the radius and the other side of the circle is also the radius. so, the radius was 3 cm, and radius + radius will give us diameter. so, 3+3=6 and 6 is the diameter. Do the same way for rest of the parts .
I hope I helped you.
