Answer:

$2.01 \: {inches}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$area \: of \: circle \: = \pi {r}^{2}$

Let pi be (3.14), the radios as given in the question is (1.6 ÷ 2 = 0.8). Therefore;

$\pi {r}^{2} = \\ (3.14) \: {(0.8)}^{2} \\ 3.14 \times 0.64 = \\ 2.0096\: or \: 2.01{inches}^{2}$

How do you simplify 14/24

Bond [772]

Answer:

7/12

Step-by-step explanation:

Simplification is something we can do if both the numerator and denominator are divisible by the same number.

In 14/24, both numbers are divisible by 2.

So, we divide both the numerator and denominator by 2. We get 7/12.

STALIN [3.7K]

The length of both rooms is 10 meters and the width for the kitchen is 5 meters, while the one for the dining room is 9 meters.

<h3>How to find the length of the rooms?</h3>

Both rooms have the same length but different areas and different widths. This common measurement can be found using the GFC or the greatest common factor. To do this, divide each number by 1,2,3, etc., and find the greatest common number (only integers are valid).

50: 50 25 10 5 1
90: 90 45 30 18 15 10 9 6 5 3 2 1

The greatest common number is 10, so 10 meters is the length of the room.
