Answer:

27is answer

Step-by-step explanation:

x+ x - 14 = 40

or, 2x = 40+ 14

or, 2x = 54

or, x = <u>5</u><u>4</u>

2

or, x= 27

What is the volume of the oblique cylinder rounded to the nearest cm^3?
SVETLANKA909090 [29]

Answer: 32009355.90cm^3

Step-by-step explanation:

Formula: V=Bh\\

Since the base is a circumference, we can replace B for the area of a circumference formula.

V=\pi r^2h

What we have here is 12 ft as the diameter of the circumference. A diameter is twice the radius, therefore we can conclude that if we take the diameter and divide it by 2, it will give us the radius.

12/2=6ft this is the radius.

Now plug all this information into your formula.

V=(3.14)(6ft)^2(10ft)\\V=(3.14)(36ft^2)(10ft)\\V=1130.40ft^3

Our values are in feet but the question requires cm. Let's convert from ft^3 to cm^3.

Normally, our conversion factors are raised to the power of 1, but in this case it's raised to the power of 3. So, first let's see how many cm are 1 ft.

1ft=30.48cm

Here is where magic comes. We can raise both to the power of 3, in order to find the cubic ft and cm that we need as our conversion factors.

(1ft)^3=(30.48cm)^3\\1ft^3=28316.8cm^3

Now we have our conversion factors.

1130.40ft^3(\frac{28316.84cm^3}{1ft^3})=32009355.90cm^3

The measure of EC is 1 ft.

Solution:

Given data:

AD = 8 ft, DB = 2 ft, AE = 4 ft

To find the measure of EC:

Using triangle proportionality theorem,

<em>If a line is parallel to one side of a triangle intersects the other two sides, then it divides the two side proportionally.</em>

$\frac{AD}{DB} =\frac{AE}{EC}

$\frac{8}{2} =\frac{4}{EC}

Do cross multiplication.

8EC=2\times 4

8 EC = 8

Divide by 8 on both side of the equation, we get

EC = 1

EC = 1 ft

Hence the measure of EC is 1 ft.
