Answer:

42.4

Step-by-step explanation:

1) use this formula of Area of the triangle:

$A=\frac{1}{2} a*b*sin(a,b)$

2) using the formula described above:

A=0.5*14*11*0.55≈42.4 (mm²)

Please Help!!!!!!!!!!!!!!!!!!!!!!!!!!!

Brums [2.3K]

Answer:

Assuming the problem asks to rotate counterclockwise: E' (0,0) F' (0,5) G' (-4,5) H' (-4,0)

If it says rotate clockwise then your points will be: E' (0,0) F' (0,-5) G' (4,-5) H' (4,0)

Step-by-step explanation:

Translate the points first by subtracting 3 from the x-coordinates of each, then subtracting 3 from the y-coordinates of each. Next, to rotate them counterclockwise about the origin 90 degrees, switch the x and y coordinates and the sign of the resulting x-coordinate. To rotate clockwise 90 degrees switch the x and y still but change the sign of the resulting y coordinate.

Determine the area of the triangular ABC with AC=5cm and height DB=30 mm.<br>

Lady_Fox [76]

Answer:

750 mm²

Step-by-step explanation:

<h3>Area of triangle:</h3>

To find the area of the triangle, multiply the base and height and then divide the result by 2.

$\sf \boxed{\bf Area \ of \ triangle = \dfrac{1}{2}*base *height}$

base = AC = 5 cm = 50 mm

height = DB = 30 mm

$\sf = \dfrac{1}{2}*50*30\\\\= 25 *30\\\\= 750 \mm^2$

Three spherical balls with radius r are contained in a rectangular box. two of the balls are each touching 5 sides of the rectan

olganol [36]

Answer:

The volume of the space between the balls and the rectangular box is $4r^{3}(6 - \pi)$

Step-by-step explanation:

The attachment below shows the description of the rectangular bow and the three spherical balls.

From the description,

Two of the balls are each touching 5 sides of the rectangular box, say the 5 sides touched by one of the balls are sides 1,2,3,4, and 5; then the other ball will touch sides 2,3,4,5, and 6).
The middle ball also touches four sides of the rectangular box, These four sides touched by the middle ball will be sides 2,3,4, and 5.

This means the balls are tightly fitted into the rectangular box.

Each of the balls has a radius r

Hence, The volume of one of the balls is given by the volume of a sphere

$Volume of a sphere = \frac{4}{3} \pi r^{3} \\$
