Answer:
(0,-3)
Step-by-step explanation:
The y digit changes when flipping over the x-axis
If the diameter is 9 cm the radius is 4.5 cm (half the diameter). The area of a circle is given by the formula: 4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).
3.14 cm x 4.5 cm = 14.13 cm^2. Remember, the units must be squared to represent area. 14.13 is extended to the nearest hundredth.
Answer:
-60+30=(-30)
Step-by-step explanation: The whale was swimming 60 feet BELOW sea level. That's negative. Then it swims up 30 feet, that's positive. Add to get -30, since -60 is the greater number although not in value. you get -30, so move the dot up , and the whale is now 30 feet below the surface.

Adjacent so that means 1 wall will be shared
each square has 4 sides,
but they share a side so 4+4-1=7 sides total
200 divided by 7 sides=200/7 ft per side
the area of a square is side^2
side=200/7
so area=(200/7)^2=40000/49
that's for 1 square
times 2
80000/49 square feet
about 1632.6530612244897959183673469388 square feet
rounded is 1633 square feet
