Answer 2

Answer:

The circumference of the garden is $15.4\pi$ meters.

Step-by-step explanation:

The garden is circular. Also, it is given that the diameter of the garden is 15.4 meters.

The circumference of the garden can be calculated using the formula of the circumference of a circle. That is,

Circumference of the garden $= \pi \ d= \pi\times 15.4= 15.4\pi$

where $d$ represents the diameter of the circle. If we take the value of $\pi$ as 3.14, then the circumference is

Circumference = $15.4\times 3.14=48.356 \ m$.
