Find the circumference of a circle:

whose radius is 3 ½ in. (22/7)

whose diameter is 3.6 (3.14)

1. 22 in

2. 11.304 units

Step-by-step explanation:

Formulas for the circumference are

C = 2πr

C = πd

___

1. Put the given numbers in the appropriate formula:

C = 2·(22/7)·(7/2 in) = 22 in

__

2. Put the given numbers in the appropriate formula:

C = 3.14·3.6 = 11.304 . . . units

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
