Calm down.
The area of a circle is defined by the following formula:
where π is a constant roughly equal to 3.1415 and r is the radius of the circle.
The radius is given as *4 ft*, so just plug it into the formula.
For number 7, x is smaller than 9, for number 8, x is bigger than 8.
Answer:
soil, rocks, and water
Step-by-step explanation:
All 3 of those are abiotic parts
1.) v=(l)(w)(h)
V=(9)(9)(9)
V=(81)(9)
V=729in^3
2.) (I forget if this is the real equation to this but this would give you the same answer)
V=(l)(w)(h)

V=576/2
V=288cm^3
