What is the difference between radiant energy and conduction?

1 answer:

6 0

Convection, is a transfer between a solid, liquid, gas, like an oven in a room. Sunlight is suppose to be radiation, but if one looks at the sun as being the oven, and the air around us as being the gas, how is that different from being convection?

The volume of a cone is 3.7x3 cubic units and its height is x units.

Serjik [45]

Answer:

$r = x\sqrt{3.54}$

Explanation:

The options are not well presented; However, the solution is as follows

Given

Shape: Cone

$Volume = 3.7x^3$

Height = x

Required

Find the radius of the cone

The volume of a cone is:

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

Where h represents height and r represents radius;

Substitute x for h and $3.7x^3$ for Volume

$\frac{1}{3}\pi r^2 * x = 3.7x^3$

Multiply both sides by 3

$3 * \frac{1}{3}\pi r^2 * x = 3.7x^3 * 3$

$\pi r^2 * x = 3.7x^3 * 3$

$\pi r^2 * x = 11.1x^3$

Multiply both sides by x

$\frac{\pi r^2 * x}{x} = \frac{11.1x^3}{x}$

$\pi r^2 = \frac{11.1x^3}{x}$

$\pi r^2 = 11.1x^2$

Take π as 3.14

$3.14 * r^2 = 11.1x^2$

Divide both sides by 3.14

$\frac{3.14 * r^2}{3.14} = \frac{11.1x^2}{3.14}$

$r^2 = \frac{11.1x^2}{3.14}$

$r^2 = 3.54x^2$

Take Square root of both sides

$\sqrt{r^2} = \sqrt{3.54x^2}$

$r = \sqrt{3.54x^2}$

Split the square root

$r = \sqrt{3.54} * \sqrt{x^2}$

$r = \sqrt{3.54} * x$

$r = x\sqrt{3.54}$
