Find the circumference of each circle. Use your calculator's value of p. Round your answer to the nearest tenth. please help

The circumference is 33.284 cm

Step-by-step explanation:

The equation to find the circumference use the fomula to find it.

3.14 is the simplified version of Pi (I SUGGEST TO USE YOUR CALCULATOR)

C = 2*pi*R /// Circumference = 2 times pi times Radius.

C = 2 * 3.14 * 5.3

C = 6.28 * 5.3

C = 33.284

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
