Answer:

Volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π

Step-by-step explanation:

Given: Diameter is 9 cm

Height is 15 cm.

First lets find out the radius of cylinder.

As given, diameter is 9 cm

we know, radius= $\frac{diameter}{2}$

Radius= $\frac{9}{2} = 4.5\ cm$

Now, finding the volume of the cylinder.

Formula; Volume of cylinder= $\pi r^{2} h$

where r is radius and h is height of cylinder.

⇒ Volume of cylinder= $\pi \times 4.5^{2} \times 15$

⇒Volume of cylinder= $\pi \times 20.25\times 15$

⇒Volume of cylinder= $303.75\pi$

Taking π = 3.14

⇒ Volume of cylinder= $303.75\times 3.14$

⇒ Volume of cylinder= 953.77 cm³

Hence, volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π.

Bob needs to save at least 10 dollars to buy that book
he gets 2 dollars in allowance every day
he has 3 dollars now
in how many days will he be able to buy the book?

translation
if d=number of days
then
how much has now+how much will earn≥10
3+2d≥10
solve
minus 3 both sides
2d≥7
divide both sides by 2
d≥3.5
but wait, you can't have 3.5 days, round up becuase if round down you wil have less than $10

answer is 4 days

that is an example, just read it and don't just report it

Given the cosine equation y = 2cos(4x) - 1, What is the midline?

pogonyaev

Answer:

$y = 2 \cos(4x) - 1 \\ when \: y = 0 \\ \cos(4x) = \frac{1}{2} \\ 4x = 60 \\ x = 15 \\ when \: x = 0 \\ y = 2 - 1 = 1 \\ intercepts = > (15, \: 0) \: and \: (0, \: 1) \\ midpoints : ( \frac{15 + 0}{2} , \: \frac{0 + 1}{2} ) \\ = (7.5, \: 0.5) \\ gradient = \frac{1 - 0}{0 - 15} \\ = - \frac{1}{15} \\ y = mx + c \\ at \: (7.5, \: 0.5) \\ 0.5 = - \frac{1}{15} \times 7.5 + c \\ 0.5 = - 0.5 + c \\ c = 1 \\ \therefore \: y = - \frac{1}{15} x + 1 \\ = > 15y = - x + 15$
