Solve the formula c = pi d for d A. d = pi c
B. d = c/pi
C. d = c - pi
D. d = pi/c

B

Step-by-step explanation:

We want to solve for d.

Our given equation is C = πd, where π and d are multiplied together.

In order to solve for d, we need to isolate it; in other words, we need to move the π to the left side with C. To do so, we must "undo" the multiplication; and what's the "undo" for multiplication? It's just division.

Thus, we simply divide both sides by π to get:

d = C/π

Our answer is thus B.

step-by-step explanation:

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
