Answer:

500π ≈ 1570.796

Step-by-step explanation:

diameter = 10

radius = diameter / 2 = 10 / 2 = 5

height = 4 * radius = 4 * 5 = 20

volume = π * height * (radius)² = π * 20 * (5)² = 500π ≈ 1570.796

Answer:

1570.8 in ^3

Step-by-step explanation:

The radius of a circle is simply half the diameter so the radius is 5.

10/2=5

Therefore, the height is 20

4x5=20

The formula for the volume of a cylinder is πr^2h

π = π

r= radius

h=height

so π(5)^2(20) = 1570.796327 in ^3

for sig figs, 1570.8 in ^3

hope this helps :)

Write in simplest form. 1/6 divided by 6 divided by 6
tensa zangetsu [6.8K]

Answer:

1/216

Step-by-step explanation:

I am pretty sure this is correct

you have to make the whole number 6 into a fraction 6/1

now it is 1/6 divided by 6/1 but you need to do KCF keep change flip

so now it is 1/6 times 1/6 and you get 1/36

then turn 6 into a fraction again

then KCF

Now it is 1/36 times 1/6 and you get 1/216

Write the expression as the sine, cosine, or tangent of an angle. sin 5x cos x - cos 5x sin x
mrs_skeptik [129]

Answer:

sin 5x cos x - cos 5x sin x = sin(4x)

Step-by-step explanation:

Given that the trigonometric expression,

sin 5x cos x - cos 5x sin x

Here we use the "sum and difference formulas"

Sum and Difference Formulas

sin(A+B)=sin A cos B + cos A sin B

sin(A-B)=sin A cos B - cos A sin B

cos(A+B)=cos A cos B - sin A sin B

cos(A-B)=cos A cos B + sin A sin B

So,

sin 5x cos x - cos 5x sin x = sin (5x - x)

sin 5x cos x - cos 5x sin x =  sin(4x)

That's the final answer.

If the difference of two numbers is 7 and their product is 60, what are they?
user100 [1]
X - y = 7.....x = y + 7
x * y = 60

y(y + 7) = 60
y^2 + 7y = 60
y^2 + 7y - 60 = 0
(y + 12)(y - 5) = 0

y + 12 = 0
y = -12....not this one because it is negative

y - 5 = 0
y = 5 <===

x - y = 7
x - 5 = 7
x = 7 + 5
x = 12 <==

so ur 2 numbers are 12 and 5

A movie complex is showing the same movie and three theaters in theater and a 60 of the 80 seats are taken and theater B 42 seat
Anna [14]

Answer:

Theatre C.

Step-by-step explanation:

Theatre A:

60 of the 80 seats are taken.

% seats taken = seats taken/total seats * 100

= 60/80 * 100

= 75%

Theatre B:

Total seats = number of seats taken + number of empty seats

= 42 + 18

= 60

% seats taken = seats taken/total seats * 100

= 42/60 * 100

= 70%

Theatre C:

Total seats = number of seats taken + number of empty seats

90 = X + 18

X = 72

% seats taken = seats taken/total seats * 100

= 72/90 * 100

= 80%

Theatre C with 80% of seats taken.
