The area of a triangle is found with 1/2(b x h). 
a = 1/2(4 x 14) 
Multiply 4 by 14. 
a = 1/2(56) 
Multiply 56 by 1/2. 
a = 28 
The area of the triangle is 28 square units, hope this helps!

siniylev [52]

Answer:

The ratio of the area of the school banner to the area of the sign is <u>1944 cubic inches : 192.61 cubic inches.</u>

Step-by-step explanation:

Given:

A rectangular school banner has a length of 54 inches and a width of 36 inches. A sign is made that is similar to the school banner and has a length of 17 inches.

Now, to find the ratio of the area of the school banner to the area of the sign.

Dimensions of school banner :

Length = 54 inches.

Width = 36 inches.

Dimension of school sign:

Length = 17 inches.

So, to we find the width of sign by using cross multiplication method:

Let the width be x.

So, 54 is equivalent to 36.

Thus, 17 is equivalent to x.

\frac{54}{36} =\frac{17}{x}

By cross multiplying we get:

54x=612

Dividing both sides by 54 we get:

x=11.33\ inches.

Thus, the width of sign = 11.33 inches.

Now, to get the ratio of the area of the school banner to the area of the sign:

Area of the school banner : Area of the school sign.

= 54\times 36:17\times 11.33

= 1944:192.61

Therefore, the ratio of the area of the school banner to the area of the sign is 1944 cubic inches : 192.61 cubic inches.

If the volume of the figure below is 4,069.44ft3 find the missing dimension
olga_2 [115]

Answer:

x = 9 ft

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the radius is x

4069.44 = pi x^2 16

Divide each side by 16 pi

4069.44 / 16 pi = x^2

Using 3.14 for pi

81 = x^2

Take the square root of each side

sqrt(81) = sqrt(x^2)

x = 9
