You can convert each of these numbers to inches, dividing by 2.54.
Area : 44cm² Perimeter : 30cm
To calculate the perimeter of a rectangle, you need to add together the length of each side of the rectangle. For a rectangle that is 11cm x 4cm, you would add these numbers together, then multiply it by 2 (this is because there are two sides that are 11cm and two sides that are 4cm). Thus: (11+4) x 2 = 30cm.
The ball used in table tennis has a diameter of d = 40 mm. Some time ago it was 38 mm. 40mm=4cm, 4cm/(2.54cm/in)=1.575 (rounded) inches
1cm = 10mm, so 4cm = 40mm. 1m = 100cm or 1000mm.
It is an equilateral triangle
Area : 44cm² Perimeter : 30cm
change centimeters into inches. 1 cm = 0.39 in. since you're calculating an area you'll get the result in inches squared!!! 11 cm x 4 cm = 4.29 in x 1.56 in = 6.69 inches squared
1,574803149606299 in
Its base is: 44/4 = 11cm
4cm is a unit of length, so 4cm is 4cm long... but if you were asking how long 4cm is in inches, 4cm = about 1.5748031 inches
1.57480315 inches

40mm - 15cm = 25
4 cm = 1.575 inches
if number is in inches, its 4cm exactly
4 centimeters is ~1.57 inches.
About 4cm in average.
