Since 36 identical coins are stacked vertically on top of each other, each with a thickness of 1.45 mm, the total height is obtained by multiplying the number of coins by the thickness of a single coin. Calculating 36 × 1.45 yields 52.2 mm.

Since 36 identical coins are stacked vertically on top of each other, each with a thickness of 1.45 mm, the total height is obtained by multiplying the number of coins by the thickness of a single coin. Calculating 36 × 1.45 yields 52.2 mm.

To convert millimetres to centimetres, divide by 10 because 1 cm = 10 mm. Dividing 52.2 by 10 moves the decimal point one place to the left, giving 5.22 cm.

Dant thickness of a rupee coin is 1.45 mm what is the total height of the cylinder formed by placing 36 rupees coin one over the other had the answer in centimetre

Answer: $5.22\text{ cm}$

Step-by-step solution

Step 1: Calculate the total height in millimetres

Since $36$ identical coins are stacked vertically on top of each other, each with a thickness of $1.45\text{ mm}$ , the total height is obtained by multiplying the number of coins by the thickness of a single coin. Calculating $36 \times 1.45$ yields $52.2\text{ mm}$ .

Step 2: Convert the total height to centimetres

To convert millimetres to centimetres, divide by $10$ because $1\text{ cm} = 10\text{ mm}$ . Dividing $52.2$ by $10$ moves the decimal point one place to the left, giving $5.22\text{ cm}$ .
