How do I add a radius syntax to gamerule commands in Minecraft?
I was wondering how to add a radius to:/gamerule doMobspawning false.
I've tried doing it like this: /gamerule doMobspawning[r=200] false, but it doesn't seem to work.

You unfortunately can't set gamerules to a specific area- they are global and apply to every part of your world.
What you want to do is to set up a command block loop and run this command:
/kill @e[r=20,type=!Player]
20 is the radius.
But it will kill friendly mobs/horses too. Do this to avoid that:
Run this in chat once:
/scoreboard objectives add blackList dummy
then make a redstone clock and add as much as (but must be enough to hold them all, so you need 14) command blocks you want to it, put one line on every command block:
/scoreboard players set @e blackList 1
/scoreboard players set @e[type=Player] blackList 0
/scoreboard players set @e[type=ArmorStand] blackList 0
/scoreboard players set @e[type=EntityHorse] blackList 0
/scoreboard players set @e[type=Villager] blackList 0
/scoreboard players set @e[type=Bat] blackList 0
/scoreboard players set @e[type=Cow] blackList 0
/scoreboard players set @e[type=Pig] blackList 0
/scoreboard players set @e[type=Rabbit] blackList 0
/scoreboard players set @e[type=Villager] blackList 0
/scoreboard players set @e[type=Chicken] blackList 0
/scoreboard players set @e[type=Squid] blackList 0
/scoreboard players set @e[type=Sheep] blackList 0
/kill @e[score_blackList_min = 1, r = 20]

You can't. There are other things that you can do at a more localized level, but /gamerules are global and effect the entire world.
But if preventing mob spawning in a particular area is what you want, you can set up a kill command on a fast (preferably 20Hz) clock. For instance, you would use the command kill @e[0,64,0,200,type=Zombie] to continuously kill any zombie that spawns or wanders into the area that's within 200 blocks of [0,0].
