The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
$A=\pi r^2 = \pi\frac{d^2}{4}$

hence the volume is
$V= \pi r^2 L = \pi \frac{d^2}{4} L$

the Length "L" is 36 in
the diameter "d" is 3 in

PLS HELP ME ASAP FOR QUESTION 4!!! (MUST SHOW WORK!!) + LOTS OF POINTS!! *branliest*

No solution because if you distribute -4 to both 2.5y and -3.25 your equation becomes -10y+13-15 1/4=-10y. Then you subtract both 13 and 15 1/4 and get -2.25 so your equation becomes -10y-2.25=-10y. After that you add 10y to both side so your equation becomes -2.25=0 which has no solution.

Xavier streamed 6 movies for $75 from his cable provider. Write an equation to find the cost, c, of each movie.]

Semmy [17]

Answer:

A: 6c=75 If there were 6 movies then 6 times the cost of each movie would equal 75.

B:$12.50 We divide 75 by 6.

C: d+75=100 the cost left on the card plus 75 will equal 100.

D: $25 We subtract 75 from 100

Hope this helps :)

I do not understand this problem

Vesnalui [34]

Answer:

16c² + 32cd + 16d²

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients. For example, $4x^3+3x^2+6x-4$ is an example of a cubic polynomial.

Area of a square = side length x side length

Therefore, given the side length of this square is 4c + 4d, then the area can be expressed as:

area = (4c + 4d) x (4c x 4d) = (4c + 4d)²

If we expand the brackets we get:

area = 16c² + 32cd + 16d²

Please help me! my teacher didn't teach me this!!

Answer:

skew

parallel

Step-by-step explanation:

First see the below figure to understand parallel and skew lines

As you can see parallel lines lie on the same plane

skew lines lie on different plane and do not intersect

1)AB and GF

AB lies on ABCD plane

GF lies on EFGH plane

and they will never meet / intersect

so skew

2)DH and BF

DH lies on ADHE plane

BF lies on BCGF plane

they seem parallel but they are on different plane, so skew

3)EF and HG

EF and HG both lie on the same plane EFGH

and they both are parallel

4)for this see the second picture

both these planes are parallel

Hope this helps!
