Answer: 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

Answer:
or
rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : = 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :210 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = or
rounded to the nearest tenth
