Question

A state 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 .)

Answer 1

The area of a circle by definition is given by:
 A = pi * r ^ 2
 Where,
 r: radius
 Substituting the values we have:
 A = (3.14) * (15) ^ 2
 A = 706.5 mm ^ 2
 Answer:
 The approximate area of the compass is:
 A = 706.5 mm ^ 2
