The circumference of a circle with a diameter of 10 is: 31.416. (Circumference = Pi x diameter)

you do 6 times piwhich is 3.14

so 8 x 3.14 = 25.12 xx

The circumference is 50.894

x2 + y2 = 64

Just multiply the diameter by pi.

The circumference of a circle when the diameter is 30 is: 94.25

if you want me to answer this i need to know the shape, or dimensions

OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
