The centroid divides the median into a 2:1 ratio. So, 9x-9=4x+16. We solve and get x=5. Therefore, OB is 36, and BE is half, 18.
Answer:
125.6 cubic meters
Step-by-step explanation:
To calculate the volume of the cylinder, we will do it as follows:
Vc = Base area * Height
We know that the base of the cylinder is a circle, therefore:
Base area: pi * r ^ 2
replacing we have:
Vc = pi * (r ^ 2) * h
We have r = 2 and h = 10, we replace:
Vc = pi * (2 ^ 2) * 10
Vc = 40 * pi
pi = 3.14
Vc = 40 * 3.14
Vc = 125.6
Which means that the volume of the cylinder is 125.6 cubic meters
Can someone please help me too no one Answerss my question

Answer:
Area: 
Perimeter: 
Step-by-step explanation:
<u>Area</u>
The area of the entire rectangle that is 4b by 
is found using A = l*w. If w=4b and l=
then the area is:
However there is a cutout in the middle. Find the area of the cut out and subtract from the total area.
The cutout is 
by b. So the area is:
Subtract 
<u>Perimeter</u>
The perimeter is the distance around the entire figure. To find it, add each side length. Then add like terms together.
