Answer:

The first one is 145 in^2 and the other is 250 in^2

Step-by-step explanation:

For the first one you have to find the base first so 5*5=25, then you find the area of the other faces and since theres 4 of them dont bother diving them by 2 and just do it twice, so the faces would be 120 in^2 in all add it together and you get 145

For the second one its the same thing but instead of a square base its a triangle so theres only 3 faces. 8*10 = 80/2 =40, 2 of the faces are 140 in all and to find the last one just 14*10=140/2=70 and you add them together and get 250

Help please<br> Find the area of the following colored regions?

Svet_ta [14]

Answer:

Area = 77.1

Step-by-step explanation:

The are of a right triangle is

$\frac{1}{2} \times base \times height$

our base and height are 6 for both triangles, so we shall find the area of one of the triangles...

$\frac{1}{2} \times 6 \times 6 = 18$

multiply this by 2

$2 \times 18 = 36$

Now find the area of the whole circle

$area = \pi {r}^{2}$

our radius is 6, therefore:

$area = \pi {6}^{2} = 113.1$

Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer

$113.1 - 36 = 77.1$

Triss [41]

Answer:

-1/35

Step-by-step explanation:

* means multiply

because of pemdas you should do three multiplication parts first

(1/4×2/5)+(-1/6×3/2)+(3/7×2/5)

1/20 - 3/12 + 6/35

3/60 - 15/60 + 6/35

-12/60 + 6/35

-1/5 + 6/35

-7/35 + 6/35

-1/35
