Answer:
A= 254.34 m²
Step-by-step explanation:
to find area of a circle use this formula, A= r²
r²
now just plug it in
A=  9²
9²
A= 81
81
A= 254.34 m²
 
        
             
        
        
        
1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6
2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5
3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.
When working with problems like these, you need to isolate the variable on one side and get it by itself.
 
        
             
        
        
        
Answer:

- Multiply 5 by 5 to get your first parameter.

- Multiply 6 by 5 to get the denominator, or your second parameter.

- For the second fraction,  , you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same. , you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.


- The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.

Finally, the problem is solved. Now that the problem is solved, we review what we just learned <em>not through more problems, though.</em>

For the first one it is 5 x10^{8}  
and for the second one it is 0.0005 = 5 × 0.0001 = 5 × 10−4
