The volume of a cylinder is 36 pie cubic units and its height is 4 units. find its lateral area.

Answers

Answer 1

Answer: V=hpir^2
V=36pi
h=4
LA=2hpir
find r then find lateral area

36pi=4pir^2
divide by 4pi
9=r^2
sqrt both sides
3=r

LA=2hpir
LA=2*4*pi*3
LA=8*pi*3
LA=24pi

lateral area=24 pi squarea units

What’s the correct answer for this?

Can anybody help me with that ?

Answers

the total voltage across the end points is 5 V
so, Vtotal = V(thermistor) + V(resistor)
5= 2 +Vr
Vr= 3 Volt
the current passing through the Resistor I= V/ R
so I = 3/1050
I=1/350 A
while the Resistor and thermistor are series the I(total) = I(thermistor) = I(resistor) = 1/350 A
Voltage at the thermistor = 2V
so r = V/ I
then R(thermistor) = 700 ohm

The Ferris Wheel makes 12 revolutions per ride. How far would someone travel during one ride?

Answers

Answer:

$C=12{*}{\pi}{*}d$ .

Step-by-step explanation:

It is given that The Ferris Wheel makes 12 revolutions per ride.

Now, The circumference to find the distance a rider travels in 1 revolution is given as: $C={\pi}d$ where "d" is the diameter.

For 12 revolutions, the distance a rider travels is given as: $C=12{*}{\pi}{*}d$ .

1 revolution = the circumference of the wheel = (pi) x (diameter) .

12 revolutions = 12 x the circumference of the wheel = (12) x (pi) x (diameter) .

PLS HELP THNXS!!! In a survey of a sample of computer users, 10% said their computer had a malfunction that needed to be repaired by a service technician. This describes a statistic. t or f

Answers

Answer:

Yes this is true.

Step-by-step explanation:

In a survey of a sample of computer users, 10% said their computer had a malfunction that needed to be repaired by a service technician.

The number 10% is a statistic because it is based on a sample of say x computer users, not the entire population of computer users.

And sample x can be any number like 500 or 600 etc. The entire population is in millions. And, sample is a part of population.

So, the answer is true.

im fairly certain that its true because you don't know the exact number of people surveyed. If they had said "out of the 100 people we surveyed 10% had problems" that would be a Parameter because parameters are percents out of the whole. if that makes sense.

Determine the intercepts of the line.
y= 10x - 32
y-intercept:
x-intercept:

Answers

Answer:

see below

Step-by-step explanation:

To find the x intercept set y =0 and solve for x

0= 10x - 32

32 = 10x

Divide by 10

3.2 = x

The x intercept

( 3.2,0)

To find the y intercept set x =0 and solve for y

y= 0 - 32

y = -32

( 0, -32)

Answer:

(0, -32)

(3.2, 0)

Step-by-step explanation:

The line is in slope intercept form. It is easy to identify the y-intercept.

$y=mx+b$

The y-intercept is (0,-32). '-32' replaces the 'b' in the equation.

To find the x-intercept, set the value of 'y' to zero and solve for 'x'.

$0=10x-32\n\n0 + 32 = 10x-32+32\n\n32=10x\n\n(32)/(10)=(10x)/(10)\n\n(32)/(10)=x\n\n\rightarrow (32/2)/(10/2)=(16)/(5)\n\n \boxed{x=(16)/(5)}$

The x intercept is (16/5, 0).

This can also be expressed as (3.2, 0).

Hope this helps.
