Answer: 6.71, and 6.7
Step-by-step explanation:
In order to write to two decimal places, we must first calculate the square root of 45.
The square root of 45 is 6.708
Therefore, when we round, we get 6.71
In order to write to two sig figs, we remember that sig figs are the number digits without zeros on the end.
Therefore, all we take is the 6.7

Answer:
Circumference ≈ 82.9
Step-by-step explanation:
The formula for calculating the circumference of a circle is:
C = 2πr
Where 3.14 is pi (as stated on your screen)
And r is the radius.
Knowing this substitute those values
C = 2(3.14)(13.2)
Multiply 2 and 3.14.
C = (6.28)(13.2)
Multiply 6.28 and 13.2.
C = 82.9 when rounded.
Answer:
The units are always squared. The area can be found when given the diameter by first finding the radius. Circumference can be used to find area
