See a solution process below:

Explanation:

The formula for the Area of a Circle is:

#A_c = pir^2#

Substitute #32# for #r# to find the area:

#A_c = pi32^2#

#A_c = 1024pi#

If you need a number for an answer without using #pi# we can use 3.14 to represent an estimate of #pi# to the nearest hundredth giving:

#A_c = 1024 xx 3.14#

#A_c = 3215.36#

The area of the circle would be"

  • #1024pi# units

Or

  • Approximately #3215.36# units
