The diameter is 7.2. What is the circumference?

22.62 cm exactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

22.6

Step-by-step explanation:

circumference is pi x diamter so:

7.2 x pi (3.142)

=22.61

round it so 22.6

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
