Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

What is the area of a circle with a diameter of 24 meters (use 3.14 for Pi)?

Zarrin [17]

The area of a circle is represented by the equation:

$A=\pi r^{2}$

We know that the diameter is two times the radius: $d=2r$

So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:

$24m=2r$ --> $r=12m$

So then we can plug this radius in to the equation for the area of a circle:

$A=\pi (12)^{2}$

$A=144\pi$

We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:

$A=3.14(144)$

$A=452.16m^{2}$

Now we know that the area of this circle is 452.16 square meters.

TEA [102]

76 out of 80 people for David.

Therefore, 76/80 people for David.

Further simplifying, every 19 out of 20 people voted for David.

What's 19 out of 20?

20 x 5 = 100
19 x 5 = 95

95% of the club members voted for David.
