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

Diameter= 16.8

51.12

221.56

448.25

886.23

Answer 1

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)

Answer 2

Area of circle is 221.56 units ² .

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 = (Diameter)/(2)`

`Radius = (16.8)/(2)`

Radius = 8.4 units

`\pi = 3.14`

Putting all the values in the formula

`Area\ of\ circle = 3.14* 8.4* 8.4`

= 221.56 units² (Approx)

Therefore the area of circle is 221.56 units ² .
