Answer: 13.7345175425633 square feet

The rounding instructions are cut off, so it's not clear how you want to round this.

========================================================

Explanation:

The area of the square is 8*8 = 64 square feet.

The two unshaded semicircles combine to form a full circle of radius 4 ft. This circle has an area of A = pi*r^2 = pi*4^2 = 16pi square feet.

The shaded area is the result of taking the circle area away from the larger square area

shaded area = (area of large square) - (area of two semicircles)

shaded area = (area of large square) - (area of circle with radius 4)

shaded area = 64 - 16pi = exact value

shaded area = 13.7345175425633 = approximate value

   Brian can run 5 km in 18.4 minutes.  If he keeps on running at the same speed, how far can he run in 23 minutes?​
valina [46]
First you need to find how far he can run in one minute. To do that divide 18.4 by 5. I got 3.68.
Then, multiply that by 23 to see how far he can run in 23 minutes. I got 84.64

Answer:

Step-by-step explanation:

-R and C are congruent

-B and S are congruent

- That means T and A are congruent

So that means C=19 B= 56 and A= 105

remember a triangle has 180 degrees

each of those marks represent congruent figures and angles.

5-2(2x - 3) = 12<br><br> Cual es el resultado de x?
postnew [5]

Answer:

<h2>x =  -  \frac{1}{4}</h2>

Step-by-step explanation:

5-2(2x - 3) = 12

<u>Expanda los términos en el corchete</u>

Eso es

5 - 4x + 6 = 12

<u>Agrupar términos similares</u>

Envíe las constantes al lado derecho de la ecuación y aquellas con variables al lado izquierdo

Tenemos

- 4x = 12 - 5 - 6

- 4x = 1

Divide ambos lados entre - 4

<h3>-  \frac{4x}{ - 4}  =   - \frac{1 }{4}</h3>

Tenemos la respuesta final como

<h3>x =  -  \frac{1}{4}</h3>

Espero que esto te ayude

IN number 14 it should be in fraction form PLSS help and explain i will give alot of points and Brainlist
nikklg [1K]

Answer: 8/9

Step-by-step explanation:

3x/7 = 8/21, find x

Step 1: cross multiply the equation

3x × 21 = 8×7

63x = 56

Divide both sides by 63; retain in fraction.

x = 56/ 63

x = 8/9

radius is half of diameter so 9

area is radius*pi ^2 which is 88.83

circumference is diameter * pi so 18*pi = 56.55
