sphere and a cylinder have the same radius and height. The volume of the cylinder is 54 meters cubed. Amie found the volume of t

Fiesta28 [93]

Answer:

Amie should have multiplied 54 by 2/3

Step-by-step explanation:

The formula of the volume of a sphere is given by

$\frac{4}{3}\pi r^3$ , where r is the radius of the sphere.

to find the volume of the sphere, we must find $r^3$

We know that the formula of a cylinder of height h and radius r is given by

$\pi r^2h$

So $54 = \pi r^2 h$

We know that the sphere and the cylinder have the same height. Recall that the height of the sphere of radius r, is the diameter of a circle that passes through the heighest and lowest points of the sphere. Then, h=2r. This means that

$54 = 2\pi r^3$

From here, we know that $\pi r^3 = \frac{54}{2}$ .

So the volume of the sphere is $\frac{4}{3}\frac{54}{2} = \frac{2}{3}\cdot54$ .

So Amie should have multiplied 54 by 2/3.

What is the value of x?

SVETLANKA909090 [29]

The rule for secants tells you
EC·ED = EB·EA
(x+4)(x+5) = (x+1)(x+12)
9x+20 = 13x+12 . . . . . . simplify, subtract x²
8 = 4x . . . . . . . . . . . . . . add -12-9x
2 = x

The value of x is 2.
