Question

Use 3.14 for pi to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary

Answer 1

Answer:

Area of circle is 221.56 units ² .

Step-by-step explanation:

Formula

$Area\ of\ circle = \pi r^{2}$

Where r is the radius of the circle.

As given

The diameter of a circle is 16.8 unit.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{16.8}{2}$

Radius = 8.4 units

$\pi = 3.14$

Putting all the values in the formula

$Area\ of\ circle = 3.14\times 8.4\times 8.4$

                                = 221.56 units² (Approx)

Therefore the area of circle is 221.56 units ² .

Answer 2

221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared. 

In this case, area = (3.14 / 4) x (16.8 x 16.8)
