Tatiana [17]

Answer:

<u>The area of the circular garden is 28.3 square feet</u>

Step-by-step explanation:

Let's recall that the area of a circle is π * r², therefore if the diameter of the circular garden is 6 feet, the area is:

Diameter = 6 feet ⇒ radius = (6/2) = 3 feet

Area of the circular garden = π * 3²

Area of the circular garden = 3.1416 * 9

Area of the circular garden = 28.2744

<u>Area of the circular garden = 28.3 square feet</u>

0.016 as a fraction in simplest form
puteri [66]
0.016 as a fraction is 16/1000 and in simplest form it is 2/125.

An easy way to figure out the fraction of a decimal is by the decimal places. As we can see, there are four numbers in our decimal (0.016). 

The first decimal place = ones 
The second decimal place = tenths
The third decimal place = hundredths 
The fourth decimal place = thousandths

We stop at the thousandths place, so basically, take 16 and put it over 1000, which looks like 16/1000.
