Answer:
153,997 Labrador Retrievers
Step-by-step explanation:
Let's make an equation for this problem. We know that there were 9,860 Great Danes. The number of Labrador Retrievers was 6,997 more than 15 times the number of registered Great Danes. More than can be changed to a plus sign. 15 times the number of Great Danes is 15 times 9,860. The equation is now 15*9,860 + 6,997.
15*9,860 is 147,900
147,900 + 6,997 is 153,997.
Answer:

Step-by-step explanation:
The circumference of a circle is given by
(1)
where:

r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

And therefore, by applying eq.(1) we can find the circumference of the circle:
