Convert: \[ 9 \mathrm{~m} 86 \mathrm{~cm}=\square \mathrm{cm} \]

To convert 9 meters and 86 centimeters to centimeters, you should remember that 1 meter is equal to 100 centimeters. Therefore, first convert the 9 meters: \[ 9 \, \text{m} = 9 \times 100 \, \text{cm} = 900 \, \text{cm} \] Now, add the 86 centimeters: \[ 900 \, \text{cm} + 86 \, \text{cm} = 986 \, \text{cm} \] So, \[ 9 \, \text{m} \, 86 \, \text{cm} = 986 \, \text{cm} \]
