The answer to 9 is 4
hope this helps:D
Answer
16
or 50.24 units
Explanation:
and r is the radius, since we know what the radius is (<em>r </em>) we can put this in to an expression
· 4² = 16 units
If the answer is not 16 then its 50.24 units
Explanation:
Now 16 is the correct answer but just in case I took this a step further.
If we estimate the area by using 3.14 which is ( ) because sometimes that isn't natural to express the area using

Answer:
Answer:
The correct list is inner core, outer core, lower mantle, asthenosphere, lithosphere.
Explanation:
Based on Structural features and chemical composition earth surface is divided into different layers. The main layers can be described as,
1. Core
2. Mantle
3. Crust
Core:
The core is further divided into inner core and outer core. The inner core is extremely hot and solid. The outer core is in fluid form and surround the inner core.
Mantle:
The mantle layer is composed of rocks. The earth's mantle is also divided into two main layers Lower mantle and upper mantle. Asthenosphere is viscous and present just below the rigid lithosphere.
Crust:
Crust is the outermost layer of earth. It is composed of variety of elements. Lithosphere is the part of Crust.

Below is the solution:
n equation showing conservation of mass of reactants and products:
<span>2H2O --> 2H2 & O2 </span>
<span>what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: </span>
<span>178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = </span>
<span>your answer (4 sigfigs): 158.8 g O2 </span>
<span>178.8 g H2O ---> 20.0 H2 & 158.8 O2</span>
