A coin has a diameter of 1.96Cm. Calculate the circumference of the coin?
To find the circumference of any circular surface all you have to do is multiple pi by the diameter; henceforth, the circumference is 6.1544 cm. 1.96 cm x pi(3.14) = 6.1544 cm
If we have a fabric piece of 10 cm by 10 cm how to calculate its GSM?
1m = 100 cm 1 sq m = 1 m × 1 m = 100 cm × 100 cm = 10,000 cm² 10 cm × 10 cm = 100 cm² → 1 sq m ÷ 100 cm² 10,000 cm² ÷ 100 cm² = 100 → weight the piece of cloth that is 10 cm by 10 cm in grams and multiple it by 100 to find out how many grams a piece of the same cloth which is 1 m by 1 m (1 square metre in area) weighs. You then know its gsm.
How many mm are there in 32 cm?
In 1 cm there are 10 mm Therefore in 32 cm there are 32 x 10 = 320 mm. Here is the metric table of length. 10mm = 1 cm 100 cm = 1 m 1000 m = 1 km. Notice each step goes up in a multiple of '10'.
