When maggie hooks her dog up to a rope that is staked in the yard, the dog can walk a distance of about 76 feet along the circumference. to the nearest tenth, what is the length of the rope?

c = 76 ft

choices
12.1 ft

24.2 ft

12.7 ft

8.1 ft

12.1

Step-by-step explanation:

76/2π

= 38/π

= 12

12.1 ft

Step-by-step explanation:

Hi, to answer this we have to apply the circumference formula:

C= 2πr

Where:

C = circumference ( in this case is 76, since the dog can walk a distance of about 76 feet along the circumference.)

r = radius. (In this case the radius is the length of the rope, because the stake is in the center of the circumference)

Replacing with the values given and solving for "r":

76 = 2πr

76 /( 2π)= 12.0957= 12.1 ft
