The units used in this question are not compatible with what they are supposedly trying to measure. As a result, it is impossible to interpret the question unambiguously.
A brick can be 200ml though most regular bricks would be more than 15 times the size. Also, from what I can understand of the question it is not the volume of the brick that matters but probably either the length and possibly the length and breadth.
Finally, a ml is a measure of volume, not area. Consequently a 2.45 ml circle cannot exist.
To create a circle out of bricks, the number of bricks required will depend on the size of the circle and the dimensions of the bricks. The circumference of the circle will determine the length of the perimeter that needs to be covered by bricks. The number of bricks needed can be calculated by dividing the circumference of the circle by the length of a single brick. This will give you an estimate of the total number of bricks needed to form the circle.

Nope... there will always be spaces around the circles - even when they're touching.
The use of concentric circles is most commonly used on a target. Concentric circles are placed around a target in which each concentric circle has the same center.
Circle around the sun some say the sun circles the planets but it does not
a circle has 4 sides
If 5 circles are inside the one circle, then the periphery is of the one circle. The periphery depends on the diameter of the one circle. The number of circles inside won't make any difference.

Because there are 360 degrees around a circle.
