Please, use the symbol " ^ " to denote exponentiation.  At first I had no idea what you meant by 3r2.  

You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches.   Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).

Sever21 [200]
<span>Find the pin number of Maritza which is between 1000 and 1500.
Find the 2 consecutive prime numbers that the product is between the given ranges.
=> Square root of 1000 = 31.6
=> Square root of 1500 = 38. 7
Now, we have the square root value of both number ranges. The only consecutive prime numbers that we have is 31 and 37 that is in 31.6 and 38.7.
=> Let us now find the product of 2 consecutive prime numbers
=> 31 x 37
=> 1147
1147 is more than 1000 but less than 1500. Thus, the pin number of Maritza is 1147.</span>
