1. To cover the path 61 gallon paint is needed.

   Step-by-step explanation:

   Given,

   The diameter of the pool = 22 yd

   The width of the ring shaped path = 5 yd

   So,

   The diameter of the outer circle = (22+5+5) yd = 32 yd

   To find the amount of paint is needed to coat the path.

   Formula

   The area of a circle with radius r is πr²

   Now,

   The radius of outer circle (R) = 16 yd

   The radius of inner circle (r) = 11 yd

   The area of the outer circle = 3.14×16² sq yd = 803.84 sq yd

   The area of the inner circle = 3.14×11² sq yd = 379.94 sq yd

   So,

   The area of the path is = (803.84-379.94) =423.9 sq yd

   1 gallon is needed to cover 7 sq yd.

   The required paint to cover 423.9 sq yd = (423.9÷7) gallon

   = 60.55 gallon = 61 gallon (approx)

   Hence,

   To cover the path 61 gallon paint is needed.

   Step-by-step explanation:

   27-10=17

   Therefore 17 is MORE THAN OR EQUAL TO 16 meaning that is not the part of the solution

   Hope this helps !!!
