∙ 7y agoArea circle = π × radius²
Area smaller circle = π × (4 cm)² = 16π cm²
Area larger circle = π × (10cm)² = 100π cm²
→ probability inside smaller circle = area_smaller_circle/area_larger_circle
= 16π cm²/100π cm² = 16/100 = (4×4)/(4×25) = 4/25.

∙ 7y agoThe probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius).
Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
A concentric circle.
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
concentric
Concentric circles, are circles within circles. Each concentric circle on the surface of a disk represents a track, the narrower the circle is, the more data can be stored on the disk.
Non concentric circles are circles that do not share the same center point.

Concentric Circles?
A concentric circle looks like a bullseye or a target. It is a big circle with littler circles inside of it with the same centerponit

A circle inside another circle is called a concentric circle. This means that the circles share the same center point, with one circle contained entirely within the other.
Non concentric circles are circles that do not share the same center point.
