The "cylinder" has a diameter of 6, and therefore its radius is half that, or 3, thus

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=3\\
h=11
\end{cases}\implies V=\pi (3)^2(11)\implies V=99\pi$

How do u find the unit rate? <br> Pls explain it with 18 miles in 3 hours <br> thx

Tomtit [17]

Let's turn this into a fraction using the given information we already have.

$\frac{18}{3} \frac{miles}{hour}$

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.

This fraction can be simplified if we divide both the numerator and denominator by 3.

Numerator: 18/3 = 6

Denominator: 3/3 = 1

Now we have

$\frac{6}{1} \frac{miles}{hour}$

Any number divided by 1 is equal to that number.

$6 \frac{miles}{hour}$

Thus, your unit rate is 6 miles per hour.

Have an awesome day! :)

Buddy is about 6inches long. It took three point five rows of stiches to make 0.5 inches in length for buddy's sweater. How many

Reptile [31]

Answer:

That is, the number of rows of stitches Buddy knitted is 42 rows.

Step-by-step explanation:

With the question, we note that the size of 3.5 rows of stitch = 0.5 inches

The size of Buddy = 6 inches

The number of rows of stitch required to make 6 inches is given by;

0.5 in = 3.5 rows

1 in = 3.5 ÷ 0.5 or 7 rows

Therefore, 6 inches is given by,

7 rows/inch ×6 inches = 42 rows

That is, the number of rows of stitches Buddy knitted = 42 rows.

the length and width of the rectangle are in ratio 4:3.If the perimeter of the rectangle is 56 m find the length and width of th

nlexa [21]

Answer:

length = 4x

width = 3x

perimeter = 56 m

also, perimeter = 2 (length + width) [from formula]

therefore, 2(4x + 3x) = 56m

2(7x) = 56m

14x = 56m

x = 56/14 m

x = 4m
