M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
balandron [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ M = k x r^2

Substitute in the values:

14 = k x 2^2

Divide both sides by 2^2 to find k:

k = 3.5

Substitute the new values in:

224 = 3.5 x r^2

Divide both sides by 3.5 to find r^2

r^2 = 64

Square root it:

r = 8

➶ Good Luck (:
