Answer» 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 |
