Given the figure in the attached image.
Circle O has diameter FG and chord FH.
If arc GH is;
we want to find the measure of angle HFG.
Recall that from circle geometry theorems;
"The angle at the center of a circle is twice the angle at the circumference of the circle."
So;
substituting the value of GH;
Answer:
176 square yards
Step-by-step explanation:
<u><em>The picture of the question in the attached figure N 1</em></u>
we know that
The area of the walkway around the rectangular pool, is equal to the area of two trapezoids (#1 and #2), plus the area of two smaller rectangles (#3 and #4)

step 1
Find the area of the two trapezoids (#1 and #2)
simplify
we have
substitute
step 2
Find the area of the two smaller rectangles (#3 and #4)
we have
substitute
step 3
Find the area of the walkway around the rectangular pool
