Find the circumference of a circular wimming pool with a radiu of 8. 5 yard. Ue 3. 14 a an approximation for pie

Sagot :

Answer:

53 if rounding to nearest 10

53.38 if not

Step-by-step explanation:

It's pretty simple actually, let's put vocabulary though

π = pie

r = radius C = circumference

ok now the formula for circumference is,

C = 2πr

because they gave you the radius, it is very simple

plug it in.

C = 2(3.14)(8.5)

3.14 x 2 = 6.28

8.5 x 6.28 = 53.38

if you're rounding to the nearest 10 it will be 53.

welcome:)
