7. A sphere and a circular cylinder have the same radius, r, and the height of the cylinder is 2r. a. What is the ratio of the v

Nastasia [14]

Answer: (a) 2 : 3

(b) 4 :1

Step-by-step explanation:

$\\$ The Volume of a sphere is given as

$\frac{4}{3}$ $\pi$ $r^{3}$ and the volume of a cylinder is given as $\pi$ $r^{2}$ h

$\\$ The ration of their volume is the same as Volume of Sphere : Volume of Cylinder , which gives

$\\$ $\frac{4}{3}$ $\pi$ $r^{3}$ : $\pi$ $r^{2}$ h

$\\$ recall that they have the same radius and the height of the cylinder is 2r , taking this into consideration, we have

$\\$ $\frac{4}{3}$ $\pi$ $r^{3}$ : $\pi$ $r^{2}$ (2r)

$\\$ which gives 4 : 6 = 2 :3

$\\$ (b) The area of a sphere is 4 $\pi$ $r^{2}$ and the surface area of the circular cylinder is $\pi$ $r^{2}$

$\\$ The ratio then gives

$\\$ 4 $\pi$ $r^{2}$ : $\pi$ $r^{2}$ ,which gives

$\\$ 4 : 1

Consider solving the equation for x.

Anna [14]

So let's simplify the equation first.

9x + 12 - 5 = ax + b
9x + 7 = ax + b
9x - ax - b = 7

Alright now plug in the numbers for each option.
I don't feel like doing all of them but I did A (one solution) and B (no solution because the two 9x's cancel out).

A slide 15 feet long makes an angle of 330 with its vertical ladder. To the

Shkiper50 [21]

Answer:

13ft

Step-by-step explanation:

Kindly find attached a rough draft of the situation.

Step one:

Given data

The length of the slide represents the

Hypotenuse of the situation on the rough sketch

Angle =33°

Required

The height of the ladder which is the adjacent of the rough sketch represented by x

Step two:

Applying SOH CAH TOA

Cos θ= adj/hyp

Cos 33=x/15

0.84=x/15

Cross multiplying

x=0.84*15

x=12.6

To the nearest foot the ladder is 13ft tall
