In the given figure, if the lines p and q are parallel then the angles 4 and 1 form the pair of co - interior Angles that sum upto 180°,
so,
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{2x + 4 · (-1) = -6
{2x - 4 = -6 | + 4
{2x = -2 | : 2
{x = -1

You got this I believe in you!!
Answer: 2r=d
d=24.28590063
vsphere=4/3pir^3
7500=4/3pir^3
times both sides by 3
22500=4pir^3
divide both sides by 4
5625=pir^3
divide bot sides by pi
1790.4931=r^3
cube root both sides
12.142950=r
2r=d
d=24.28590063 ft
