Answer:

What is the degree of polynomial?

The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.
Example:

4x The Degree is 1 (a variable without an
exponent actually has an exponent of 1)
More Examples:
4x^ − x + 3 The Degree is 3 (largest exponent of x)
x^2 + 2x^5 − x The Degree is 5 (largest exponent of x)
z^2 − z + 3 The Degree is 2 (largest exponent of z)
A constant polynomials (P(x) = c) has no variables. Since there is no exponent to a variable, therefore the degree is 0.
3 is a polynomial of degree 0.
C = 11*(2*d) Try it and see that it fits every sample you have. Again this can be simplified to
C = 22 * d
Notice that

, so

Then taking the positive square root gives

so
and
.
31 to the 9th power (31 9... i cant make the number small lol)
Instantaneous rate of change = S'(r) = 8πr
S'(8) = 8π(8) = 64π
Therefore, the instantaneoud rate of change of the <span>surface area with respect to the radius r at r = 8</span> is 64π
