Astate map has a circle-shaped compass. if the radius of the compass is 15 millimeters, what is the approximate area of the compass? (use 3.14 for .)

 " 707 mm² "  .

The area, "A" of a circle:

A =  * r²  ; 

  in which:  "A = area of the circle" ; 
                   π = 3.14 (approximation we are given in problem; and commonly                                                                                                                     used);
                   r = radius = 15 mm (given) ;

Solve for "A" (the area of the circle) :

       A =  * r² ;

→  A = (3.14) * (15 mm)² ; 

→  A = (3.14) * (15)² * (mm²) 

→  A = (3.14) * (15)² * (mm²) ;

→  A = (3.14) * 225 * (mm²) ;

→  A = 706.5* (mm²) ;

→  A = 706.5 mm²) ;  → round to:  " 707 mm² " .
