Question

A circular walking path has a diameter of 45 yards.What is the distance around the walking path?

Answer 1

Diameter = 45 yards

Distance around the circular part = Circumference of a circle

Circumference of a circle = 2 *22/7 * Diameter/2

= 44/7 *45/2

=141.4285714 yards

Answer 2

the circumference is 2rpi or pid so since the diameter is 45 the circumference is 45pi or about 141 yrds
