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

step-by-step explanation:

you get texts and minutes, so why not

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
