A cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.

Anton [14]

Answer:

Height of cylinder is $\frac{4}{5}\ ft$ .

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

$R = \dfrac{D}{2}$

So, radius, R = $\frac{6}{2} \Rightarrow 3$ feet

Let height of cylinder be $h$ feet.

Formula for volume of cylinder is given by:

$V = \pi R^{2} H$

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

$V = \dfrac{36 \pi}{5} ft^{3}$

Using formula for volume, $V = \pi R^{2} H$

$\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft$

Hence, Height of cylinder is $\frac{4}{5}\ ft$ .

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?

m_a_m_a [10]

Answer:9 nickels and 19 dimes.

Step-by-step explanation:

Let $n$ be the number of nickels Kay has.

Let $d$ be the number of dimes Kay has.

Value of $1$ nickel is $ $0.05$

Value of $n$ nickels is $ $0.05n$

Value of $1$ dime is $ $0.1$

Value of $d$ nickels is $ $0.1dn$

Given that Kay has a total of $28$ coins.

So, $n+d=28$ ...(i)

Given that Kay has a total value of $ $2.35$

So, $0.05n+0.1d=2.35$ ...(ii)

Using (i) and (ii),

$0.05n+0.1(28-n)=2.35\\0.05n+2.8-0.1n=2.35\\2.8-2.35=0.05n\\0.45=0.05n\\n=9$

$d=28-n=28-9=19$
