Answer:
The answer is 9.
Step-by-step explanation:
Because 7 + 9 + 11 + 13 = 40, 9 is the 2nd number in the problem.
Answer:
2855.0
Step-by-step explanation:
there are several surface areas.
1. outside surface of the cylinder = circle circumference times height = 2*pi*r*height = 2*pi*14*14 = 1231.5
2. top and bottom of the cylinder = circle area times 2 = pi*r^2 * 2 = pi*14^2 *2 = also 1231.5
3. subtract the 2 cut out rectangles on the top and the bottom = 2* 6*14 = 168
4. add the areas of the inside walls of the cut out block.
there are 2 narrow rectangles = 2* 6*14 = 168
there are 2 squares = 2* 14*14 = 392
so, 1.+2.-3.+4. = 2855.0 (2855.00864...)
Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example 
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1) 
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2) 
Since all of the variables have integer exponents that are positive this is a polynomial.
3) 
Not a polynomial because a term has a negative exponent
.
4) 
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
