The general form for a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) represent the centre and r represent the radius.
With centre (7, -9) and radius 3, we can simply substitute it into our form:
(x - 7)^2 + (y + 9)^2 = 3^2
(x - 7)^2 + (y + 9)^2 = 9
Answer:
120°
Step-by-step explanation:
The angle just below 'x' is 40° (alternate angles/parallel lines)
40 + x + 20 = 180 ( straight line)
x = 120°

Answer:
The volume of figure 1 is 11340 ft^3 greater than figure 2
Step-by-step explanation:
For rectangular prism, volume is
V = lenght x width x height
V = 36 x 21 x 18 = 13608 ft^3
For rectangular pyramid, volume is
V = (lenght x width x height) ÷ 3
V = (36 x 21 x 9) ÷3 = 6804/3 =2268 ft^3
Difference in volume = 11340 ft^3
