The product of two integers is equal to the product of their LCM and GCF. Hence.  

16 × N = 48 × 8  

N = 48 × 8 / 16 = 24

• If the area of a circle is 81π square feet, find its circumference.  

Solution  

The area is given by π × r × r. Hence  

π × r × r = 81π  

r × r = 81 ; hence r = 81 feet  

The circumference is given by  

2 × π × r = 2 × pi × 9 = 18 π feet
