Answer:

Hope this helped :)

Step-by-step explanation:

Convection flows structure in light of the fact that a warmed liquid grows, getting less thick. The less-thick warmed liquid ascents from the warmth source. ... For example, a hot radiator warms the air promptly around it. The air ascends toward the roof, pulling cooler air down from the roof into the radiator to be warmed.

N is a rational number.m is an irrational number.n2 cannot be an irrational number? why or why not

Korolek [52]

If n is rational, it means that

$n\in\mathbb{Q}\Rightarrow n=\frac{p}{q},\quad p\in\mathbb{Z},\quad q\in\mathbb{Z}^*$

Therefore when we do n² we can write it as

$n^2=\frac{p^2}{q^2},\quad p\in\mathbb{Z},\quad q\in\mathbb{Z}^*$

Remember that the product of two integer numbers is also an integer, therefore we can guarantee that

$p^2\in\mathbb{Z}\text{ and }q^2\in\mathbb{Z}^*$

Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number

Answer:

A. $V = (pi)(3.25)^2(12)$

Step-by-step explanation:

The formula for the volume of a cylinder is the formula for the area of the circle, times the height of the cylinder. The formula for the volume of a circle is,

$A = (pi)(r)^2$

Multiply that by the height to find the formula for the volume of a cylinder,

$V=(pi)(r)^2(h)$

Where (pi) represents the value (3.1415), (r) represents the radius, and (h) represents the height of the cylinder. Now substitute in the given values, remember, this problem gives the diameter of the cylinder, divide that value by two to find the radius.

$V=(pi)(\frac{6.5}{2})^2(12)\\\\V = (pi)(3.25)^2(12)$
