If q is inversely proportional to r squared and q=30 when r=3, find r when q=1.2

r = 3

Step-by-step explanation:

q = k /

k = q = 1.2 x 3 x 3 = 10.8

q = 10.8/

1.2 = 10.8/

r = = 3

r=225

Step-by-step explanation:

first you have to find q, so set that up and get 30=k/9

times both sides by 9 and get

270=k

the plug into the best equation

1.2=270/r

times r on both sides

1.2r= 270

divide by 1.2

r=225
