A circle inside of a square. The circle touches all sides of the square. The base is 5 centimeters.

lina2011 [118]

Answer:

19.6 cm²

Step-by-step explanation:

If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.

The area of a circle is given by:

$A= \pi \frac{d^2}{4}$

In this problem, d = 5 cm, the area of the circle is:

$A= 3.14 *\frac{5^2}{4} \\A=19.6\ cm^2$

The approximate area of the circle is 19.6 cm².

A local business has an area reserved behind the store for a parking lot that is 78 meters long by 19 meters wide. The stalls of

S_A_V [24]

The total area available for cars to park will be 858m².

<h3>How to calculate the area?</h3>

The area of the parking lot will be:

= 78 × 19

= 1482m²

The area of aisle will be:

= 8 × 78

= 624m²

The available area will be:

= 1482m² - 624m²

= 858m².

The compact parking spaces that will fit in the lot will be:

N × 12.5 = 858

N = 858/12.5

N = 68

The non compact parking spaces that will fit in the lot will be:

N × 16.5 = 858

N = 858/16.5

N = 52

stepladder [879]

Answer:

$P(80/100$

Step-by-step explanation:

We are given that

Mean, $\mu=68.5$ %=68.5/100

Standard deviation, $\sigma=8.2$ %=8.2/100

We have to find the probability that a student who wrote the examination had a mark between 80% and 100%.

$P(80/100$

We know that

$P(a$

Using the formula

$P(80/100$

$P(80/100$
