The diameter of your little finger is abouta)1.5 mmb)1.5 cmc)1.5 md)1....
Explanation:
The diameter of your little finger is about 1.5 cm.
To understand why the correct answer is option 'B', let's first understand what diameter means and how it relates to the little finger.
Diameter:
The diameter is a term used to describe the distance across a circle passing through its center. In simpler terms, it is the length of a straight line passing through the center of a circle and touching two points on its circumference.
The Little Finger:
The little finger, also known as the pinky finger, is the smallest and shortest finger on the human hand. It is located on the outer side of the hand, next to the ring finger. The little finger is made up of several bones called phalanges, which are connected by joints.
Measurement of Diameter:
To measure the diameter of the little finger, we can use a ruler or a measuring tape. Place the ruler or tape horizontally across the widest part of the finger, which is usually near the base. Note the measurement where the ruler or tape intersects the opposite sides of the finger.
Approximate Diameter of the Little Finger:
The diameter of the little finger may vary slightly from person to person, but on average, it is about 1.5 cm. This means that if you were to measure the distance across the little finger at its widest point, it would be approximately 1.5 cm.
Options Explanation:
Let's evaluate each option to understand why option 'B' is the correct answer.
a) 1.5 mm: This measurement is too small for the diameter of a little finger. It is roughly the thickness of a paperclip.
b) 1.5 cm: This is the correct answer. As explained earlier, the diameter of the little finger is approximately 1.5 cm.
c) 1.5 m: This measurement is too big for the diameter of a little finger. It is roughly the height of an average adult.
d) 1.5 km: This measurement is extremely large and not relevant to the diameter of a little finger. It is roughly the distance between two cities.
Therefore, the correct answer is option 'B' (1.5 cm), as it accurately represents the approximate diameter of a little finger.
