Mathematics

barxatty [35]3 years ago

the following formula is used to find the volume of a cone

V - volume = πr²h/3

where π = 3.14, r - radius and h - height

the height hasnt been directly given

we can find height using Pythogoras theorem for the right angled triangle given

4² + h² = 5²

16 + h² = 25

h² = 25 - 9

h² = 9

h = 3

height = 3

diameter is 4, therefore radius - diameter / 2 = 4/ 2 = 2

radius = 2

substituting values in the volume equation

V = 3.14 x 2² x 3 /3

= 12.56

volume is 12.56 cubic units

Simplify (3x – 5) + (5x + 1).
Andrej [43]

Answer:

(-2x - 6)

Step-by-step explanation:

The given expression is ( 3x - 5 ) - ( 5x + 1 )

We have to simplify the given expression

First we will open the bracket having negative notation outside.

( 3x - 5 ) - 5x - 1

3x - 5 - 5x - 1

Now we will collect the similar terms together.

3x - 5x - 5 -1

-2x - 6

So the simplified form of the expression is (-2x - 6)
