Answer 1

Answer:

circumference equals about 3.14

Step-by-step explanation:

c=2pi times r

c=2 (3.14) times 0.5

c= about 3.14

Answer 2

Answer:

3.14(rounded to nearest hundredth)

Solve by...

• First, use the formula for finding circumference by diameter;

$C = 2\pi r$

Which is the same as ↓

$2\pi r = 2 * \pi * r(0.5)$

$= 3.1415926535897932384626433832795$
