First, you can convert yards to feet, to make it easier to simplify feet to inches. There are 3ft in a yard, so you can say that there are 3ft*7+2ft. 3*7 is 21, and adding 2 to that you will have 23ft. from here you can convert that directly to inches. If there are 12 inches in a foot, you will multiply 12 by 23. Your final answer will be 276in.
R = v/4
because:
v = 4r
v/4 = 4r/4 the fours cancel out and you are left with r
therefore v/4 = r or r = v/4
