Answer:

Half of 19 = 9.5(new radius)

2 x 3.4 x 9.5 = 64.6 ft is your answer.

Formula of circumference:

2 x 3.14(pi or 22/7 depending on what they tell you to use for pi) x radius(half of diameter or given radius)

Answer:

C = 59.7

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr

R = radius

The radius is the half of a diameter, so 19/2 is 9.5.

C = 2π(9.5)

C = 59.69026041
