Question

A round patio is 14m in diameter what is the distance around the patio

Answer 1

To work out the circumference (perimeter) of a circle, we use
C = πD
This means we multiply the diameter of the circle (14) by pi (π = 22/7)
14 x π
14π = 43.98m

Answer 2

distance around the round patio is circunference of a circle
circumference=2 times radius times pi or diameter times pi
so we have
diameter=14
circumference=14 time pi
answer is 14π

if you want to aprox pi to 3.14 then
14 times 3.14=43.96 meters
