s / ( 2 pi * h) = r

Step-by-step explanation:

s = 2 * pi * r * h

Divide each side by 2 * pi * h

s / 2 pi h= 2 * pi * r * h/ ( 2 pi h)

s / ( 2 pi * h) = r

s over 2×pie×h

Step-by-step explanation:

To get the variable r by itself you need to divide the 2×pie×hr by 2×pie×h. You need to divided both sides to keep the equation true, so divide both sides by 2×pie×h to get: s/2×pie×h.

351°f

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
