Answer:

Hello,

Once we understand circumference we're almost home.

The formula is:

Circumference = pi (3.14) times diameter

So LET's find the diameter of the tower.

10 = 3.14*D

Divide 3.14 to get:

Diameter is approx 3.18 meters for the tower so we now know with the fence the diameter is 7.18 meters.So now we can find the circumstance:

Circumference = 3.14 times 7.18

Circumference = 22.55 meters approx

Step-by-step explanation:

The circumference of the tower is your 10 meters; we need to find a radius

2r%2Api+=10m

r=10+m%2F2pi

r=5m%2F3.14

r=1.59m

a fence that surrounds a tower makes a CIRCLE that will have a radius of r1=r%2B2=1.59%2B2=3.59 meters (radius MEASURED from the CENTER of the tower), and will have a circumference of:

2r1%2Api+=+2%2A3.59%2A3.14=+22.55m which is the length of a fence
