Answer: a = 2,315.5

a = 2π x 288 + 2π x 81

a = 1809.6 + 508.9

a = 2,315.5

To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in. 

F  20÷4x5
    =5x5
    =25
      
T   10+10÷2
      =10+5
      =15

F    6+4×5
      =6+20
      =26

<span>T   81÷9+2
     =9+2
     =11</span>
