The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
3 km
That depends on what you have 10864 of. If that's 10864 km, then it is already rounded to the nearest km. If it's 10864 something elses, you should tell us what it is.

To convert 9 km 700 m to the nearest kilometer, we need to consider the meters. Since 700 meters is closer to 1 km than 2 km, we round down to the nearest kilometer. Therefore, 9 km 700 m is approximately 10 km when rounded to the nearest kilometer.
12.0 KM
