How do you find the surface area if your radius is 5 and your length is 10

1 answer:

6 0

Surface Area of a Cone = (pi)*(radius)*(radius) + (pi)*(radius)*(length)

radius = 5
length = 10

SA = 25pi + 50pi = 75pi or about 235.619

It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1

3241004551 [841]

Answer:

262.12mph and 419kph

Step-by-step explanation:

Given: It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1114 miles

To Find: the average speend of the plane in miles per hour, If every mile is approximately 1.6 kilometers, the speed of the airplane in kilometers per hour

Solution:

Distance between Orlando,Florida and Boston, Massachusetts $=1114$ $\text{miles}$

Time taken to cover the distance $=4\text{hours}$ and $15\text{minutes}$

We know that,

$\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total time}}$

$=\frac{1114}{\frac{17}{4}}$

$=\frac{1114\times4}{17}$

$=262.12$ $\text{mph}$

It is given that,

$1\text{mile}=1.6\text{kilometer}$

therefore,

$1\text{mph}=1.6\text{kph}$

Speed Of plane in Kilometers per hours $=\text{speed in mph}\times1.6$

$419.4\text{kph}$

Speed of in miles per hour is $262.12$ $\text{mph}$ and Speed in kilometer per hour $419.4\text{kph}$

M (2y+19) (5x+20) n (4x-11)

AleksandrR [38]

Answer:

(5x+20)+(4x-11)=180(linear pair)

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

now,

(2y+19)+(5x+20)=180(co-interior angle)

2y+19+5×19+20=180

2y+134=180

2y=180

y=180/2

y=90

Which of the following accurately lists all discontinuities of the function below?

jeka94

Checking the discontinuity at point -4
from the left f(-4) = 4
from the right f(-4) = (-4+2)² = (-2)² = 4
∴ The function is continues at -4

Checking the discontinuity at point -2
from the left f(-2) = (-2+2)² = 0
from the right f(-2) = -(1/2)*(-2)+1 = 2
∴ The function is jump discontinues at -2

Checking the discontinuity at point 4
from the left f(4) = -(1/2)*4+1 = -1
from the right f(4) = -1
but there no equality in the equation so,
∴ The function is discontinues at 4

The correct choice is the second
point discontinuity at x = 4 and jump discontinuity at x = -2
