Volume of a cylinder can be calculated as:

V= πr²h

Values of r and h are given.
Radius = r = 2
Height = h = 6
π = 3.14

Using the values, we get:

V = 3.14(4)(6) = 75.36 cubic units

So, the answer to this question is 75.36

Park Hyatt Philadelphia at the Bellevue, located at Walnut and Broad in downtown Philadelphia has a capacity of 240 king rooms.

Reika [66]

Answer:

$X=53$

Step-by-step explanation:

From the question we are told that:

Regular fare R= $275

Discount fare of $125

Mean $\=x =50$

Standard deviation $\sigma= 26.$

Generally, the equation for Critical Fraction is mathematically given by

$C=\frac{Pf-Pd}{Pf}$

$C=\frac{275-125}{275}$

$C=0.5$

From Z Distribution Table

$Z=0.1131$

Therefore

Reservation made is give as for High fare travellers is

$X = \=x+(z* \sigma)$

$X = 50 + (0.1131 * 26)$

$X=53$

Jessica bought 3/4 lb of berries. Mary bought 1/6 lb of berries less the jessica. what is the total weight of berries in pounds

Mrrafil [7]

Given that number of pounds of berries that Jessica bought = $\frac{3}{4}$ lb

Given that "Mary bought $\frac{1}{6}$ lb of berries less the jessica"

then number of pounds of berries that Mary bought

$=(\frac{3}{4}-\frac{1}{6})$ lb

$=\frac{3}{4}\cdot\frac{3}{3}-\frac{1}{6}\cdot\frac{2}{2}$ lb

$=\frac{9}{12}-\frac{2}{12}$ lb

$=\frac{7}{12}$ lb

Now we need to find the total weight of berries in pounds that they bought.

To find that we just need to add both values.

$\frac{3}{4}+\frac{7}{12}$

$=\frac{3}{4}\cdot\frac{3}{3}+\frac{7}{12}$

$=\frac{9}{12}+\frac{7}{12}$

$=\frac{16}{12}$

$=\frac{4}{3}$

Hence final answer is $\frac{4}{3}$ lb.

Show that the line with equation 4y+3x=44 is a tangent to the circle with centre (5,1) and radius 5.

viktelen [127]

When a line is a tangent to a circle then the point of a tangent on a circle is perpendicular and also equal to the radius

So for perpendicular.

$P = \frac{ax+by+c}{\sqrt{a^2 + b^2} }$

4y + 3x - 44 = 0

So, a = 4

b = 3

c = -44

x = 5

y = 1

Putting the values in the formula, we get

P = -4.2

Since the radius of the circle 5 is not equal to P, The line is not a tangent to the circle.
