What number can be used to complete the volume statement for the cone? 4m h 3 m base

Mathematics

Mariana [72]4 years ago

The volume of a cone is calculated through the equation,

     V = (πD²/4)(H)/3

where V is volume,
     D is diameter
     H is height

Substituting the known values,

    V = (π(3m)²/4)(4m)/3

Simplifying,
    V = 3π m³

The volume of the cone is equal to 3π or 9.42 m³. The value should complete the volume statement of the cone.

Suppose y varies directly with x. If y = –20 when x = 2, find y when x = 14
Natasha_Volkova [10]

Answer:

y = -140

Step-by-step explanation:

Y varies directly with x

y = kx

We know y = -20 when x =2, we can solve for k

-20 = k*2

Divide each side by 2

-20/2= 2k/2

-10 =k

y = -10x

Now we want to find y when x = 14

y = -10 *14

y = -140

All you need to do is solve it
\frac{1}{2} ^{2} or \frac{1}{2}  x \frac{1}{2}
When solved your answer is 0.25 or 1/4
------------------------
What I did to solve it was....

1. Divide top fraction by bottom fraction to get decimal
1 ÷ 2 = 0.5

2. Then multiply 0.5 by its self (the same as putting it to the ^2)
0.5 x 0.5 = 0.25
