Question

R= 6.45. Find the area of the circle shown. Use 3.14 for π . Round to the nearest hundredth if necessary.

Answer 1

130.62

Explanation:

The formula for the area of a circle is
`\pi r^(2)`.

We use 3.14 for pi and 6.45 for r:

3.14 · 6.45²

3.14 · 41.6

130.624, rounded to the nearest hundredth 130.62

Answer 2

130.63

Explanation:

The formula for a circle is:

Area = πr²

Let's plug in our values.

Area = 3.14(6.45)²

= 3.14(41.6025)

= 130.63185

Now we round to the nearest hundredth to get 130.63.

Hope this helps and good luck on your homework!
