The value of a is between 0 and 1.
The answer is 314,000,000 ft^2
pi r^2
3.14* 10,000^2
3.14*100,000,000
314,000,000
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r =
= 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer: WY=4.4 mm
Step-by-step explanation:
WY=WX/2
WY=8.8/2
WY=4.4 mm
M=(y2-y1)/(x2-x1)
m=(-4-4)/(3-1)
m=-8/2
m=-4
so the answer should be first one
