Hello!

Since we are rounding until tenths, the answer would be 3879.

Since a tenth is the first decimal of a number, we just round it and get that.

Hope this helped! c:

The area of the circle is approximately 50

<h3>Areas</h3>

The area of a shape is the amount of space occupied by the shape

<h3>Area of circle</h3>

Given the three radius of the circle, the area of the triangle is calculated using:

$Area = \pi r^2$

From the figure, we have:

$AD = 4$ --- the radius

So, we have:

$Area = \pi r^2$

$Area = 3.14 \times 4^2$

$Area = 50.24$

Approximate

$Area = 50$

Hence, the area of the circle is approximately 50
