Question

what is length between A&B ​

Answer 1

Answer:

7 .5cm

Step-by-step explanation:

• the length that should be 1.5 cm because the half of 3 is 1.5 so after a in 3cm circle the value will be 1.5 cm
• the next in 4cm circle there should be counted 3cm because 1 cm of the circle is in place of 3cm circle so 1.5 cm + 3 cm = 4.5 cm
• in the 6 cm circle the length above the point b is 3cm because the point b is the half of the 6cm circle
• SO, 1.5 CM + 3 CM + 3 CM =7.5 CM
