2 m
28.26 m 28.3 m (rounded)
The answer depends on the radius (or diameter). Since that is not specified, there is no possible way to answer the question.
Without knowing the units of 113.47 I can't.If the units are:mm: 113.47 mm = 113.47 × 0.001 m = 0.11347 m → 0 m to the nearest mcm: 113.47 cm = 113.47 × 0.01 m = 1.1347 m → 1 m to the nearest mm: 113.47 m → 113 m to the nearest mkm: 113.47 km = 113.47 × 1,000 m = 113,470 m → 113,470 m to the nearest min: 113.47 in = 113.47 × 0.0254 m = 2.882138 m → 3 m to the nearest mft: 113.47 ft = 113.47 × 0.3048 m = 34.585656 m → 35 m to the nearest myd: 113.47 yd = 113.47 × 0.9144 m = 103.756968 m → 104 m to the nearest mfathoms: 113.47 fathoms = 113.47 × 1.8288 m = 207.513936 m → 208 m to the nearest mchains: 113.47 chains = 113.47 × 20.1168 m = 2,282.653296 m → 2,283 m to the nearest mfurlongs: 113.47 furlongs = 113.47 × 201.168 m = 22,836.53296 m → 22,837 m to the nearest mmiles: 113.47 miles = 113.47 × 1,609.344 m = 182,612.26368 m → 182,612 m to the nearest mIn each case I have looked at the digit after the decimal point and if it was 5 or more rounded up, otherwise rounded down.
1 metre = 1000 millimetres so 1.32 m = 1.2*1000 = 1320 mm. Simple!
4.5 m
435cm is nearest to 4.5m
435cm equates to 171.26"
435cm is 4.35m
4.78 m to the nearest m is 5 m.
85765.47944 m to the nearest metre is 85765 m since the tenths digit is less than 5 it rounds down. However: 85765.47944 CENTImetres *IS* 858 metres to the nearest metre. ie 85765.47944 cm to the nearest m: 100 cm = 1 m → 85765.47944 cm = 85765.47944 ÷ 100 m = 857.6547944 m → 858 m to the nearest metre as the tenths digit is 5 or more it rounds up.
4 m
9 m
0.213m to the nearest hundredths is 0.21m
That depends on the numerical value of M.
2.6 m
Mars and Venus are the planets nearest the Sun.
