18pi rounded to the nearest whole number

56.52 but you have to round so its 57

Step-by-step explanation:

You have to multiply 18 and pi so we will use 3.14 for pi. 18 times 3.14 will give you 56.52 but you have to round it so it will be 57. If the number is greater than 5 you round up but if it is less you round down.

18pi = 18*3.14 = 56.52

Round it to the nearest whole number
