A^2 + b^2 = c^2
8^2 + b^2 = 12^2
64 + b^2 = 144
b^2 = 144 - 64
b^2 = 80
b = sqrt 80
b = 8.9 ft <===
The formula for the area of a rectangle is A = bh.
Substitute 216.24 for A (area) and 15.9 for h (height).
A = bh
216.24 = b(15.9)
÷ 15.9 ÷ 15.9 Divide 15.9 on both sides.
13.6 = b
So, the base of the rectangle is 13.6 cm.
The 1st choice (x - 9, y - 3) is the correct answer.
Take any of the corresponding coordinate points to find the rule that represents the translation:
D —> D’
(3, 5) —> (-6, 2)
(3 - 9, 5 - 3) = (-6, 2)
Counting the units from graph also shows this translation rule, seeing that hexagon DEFGHI moved 9 units to the left and 3 units down.
Hope this helps :)
Answer:

Step-by-step explanation:

The area of the quarter circle with radius 3ft is 
Area of a quarter circle is given by the formula:

Where r represents the radius of the circle
In the quarter circle shown, the radius, r = 3 feet
π = 3.14
Substitute π = 3.14 and r = 3 into the formula 

The area of the quarter circle with radius 3ft is
