Question

An automobile tire has a diameter of 59m. What is the circumference of the tire

Answer 1

185.4m (rounded to 1dp)

Circumference of a circle is the diameter times by pi. 59×pi=185.4

Answer 2

59 meters

or approximately 185.26 ( using 3.14 for pi)

or 185.3539666 meters using the pi button

Explanation:

The circumference is given by

C = pi *d where d is the diameter

C = pi * 59 m

C = 59 pi meters

We can approximate pi by 3.14

C =185.26 meters

or by using the pi button the calculator

185.3539666 meter
