Lets get started :)

The Volume formula of a Cylinder is 
V = \pir²h
(r = radius, h = height)

The radius given is 8 and the height is 4, We can plug in the known values

V = \pi(8)²(4)
   = \pi256
   = 256\pi units³ (You can leave the answer in this form)
   ≈ 804.2 units³ (approximately)

Units³ because it is a volume (3D shape)

Hatshy [7]

Answer:

(3, 2) is the ordered pair for the given system of equations.

Step-by-step explanation:

Given:

2 x+ y = 8.......................(i)

y = - x + 5........................(ii)

<u>Put y = - x + 5 in equation (i)-</u>

<em>2 x + ( - x+ 5) = 8</em>

<em>2 x - x + 5 = 8</em>

<em>x = 8 - 5</em>

<em>x = 3</em>

<u>Now put x = 3 in equation (ii)-</u>

<em>y = - 3 + 5</em>

<em>y = 2</em>

Hence the (3, 2) is the correct ordered pair.

Point J is located at (2,5)(2,5) and point K is located at (4,19)(4,19).
Anni [7]
We have the coordinates
J (2,5)
K (4,19)

Since we are to find the point that partitions the line segment into 3:2 ratio, we have 5 equal parts of the line segment. So,

Get the horizontal distance:
4 - 2 = 2
Divide by 5
2/5
Multiply by 3
2/5 x 3 = 1.2
Add this to the x coordinate of J
2 + 1.2 = 2.2

Get the vertical distance:
19 - 5 = 14
Divide by 5
14/5
Multiply by 3
14/5 x 3 = 8.4
Add this to the y coordinate of J
5 + 8.4 = 13.4

The coordinates of the point is
(2.2,13.4)
