Step-by-step explanation:

Given

Volume (V) = 313 in³

π = 3.14

Height (h) = 16 in

Radius (r) = ?

We know.,

Volume of cone (V)

$313 = \frac{1}{3} \pi {r}^{2}h$

$313 \times 3 = 3.14 \times 16 \times {r}^{2}$

$939 = 50.24 {r}^{2}$

$18.69 = r^{2}$

$r = \sqrt{18.69}$

r = 4.32 in

Natali5045456 [20]

15=pants
d less than pants means
15-d

5 of them
5(15-d)=cost of shirts

so total cost=15+5(15-d)

Determine whether the statement is true or false, and explain why.

Answer:

False

Step-by-step explanation:

In this case, i woudnt reccomend to use integration by parts, becuase you are not simplifying the expression by doing an integration and a derivation. It is not easy to integrate 1/x³+1, and if you derivate it, then a natural logarithm would appear, and the integral wont be easier after this parts step.

It is a better idea to use integration by substitution. Note that if you replace x³+1 by a variable y, we have that dy = 3x² dx. We can easily make a 3xdx appear in the integral by multiplying and dividing by 3, solving the integral easily:

$\int\limits_0^1 x^2/x^3+1 \, dx = 1/3 * \int\limits_1^2 du/u = (ln(2) - ln(1) )/3$
