Answer 1

Answer:

10. 91.08mm

11. 33.12in

12. 41.4yd

Step-by-step explanation:

To find the answer to each, we first need to calculate the circumference:

(use 3.14 for π)

(2 * Diameter) * π = Circumference

Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.

(Circumference / 2) + Diameter

Do this for each semi-circle as shown here:

10. (2 * 22) * 3.14 = 138.16

(138.16 / 2) + 22 = 91.08

11. (radius is given so double the middle)

(2 * (2 * 4)) * 3.14 = 50.24

(50.24 / 2) + 16 = 33.12

12. (2 * 10) * 3.14 = 62.8

(62.8 / 2) + 10 = 41.4
