Answer:
The volume of the cylinder is about 1256.6 cubic meters.
Step-by-step explanation:
The volume of a cylinder is given by the formula:

Where <em>r</em> is the radius and <em>h</em> is the height.
Our radius is 10 meters and our height is four meters. Substitute:

Evaluate:

Thus, the volume of the cylinder is about 1256.6 cubic meters.
Step-by-step explanation:
Sorry I cant get any more answers but I really hope that this helps
I think its 1.25ft but i could be wrong... sorry if im wrong
Firstly, we need to draw triangle
we know that
O is a centroid
and centroid divides median into 2:1
so,

we have FO=4
so, we can plug it


now, we can find CF
CF=OC+FO
CF=8+4
CF=12
now, we can see triangle ACF is a right angled triangle
so, we can use pythagoras theorem

now, we can solve for x



Since, it is equilateral triangle
so,

we know that
E is a mid-point
so,

now, we can plug values
