The volume of a cone is given by v=13πr2h. If a cone has volume 3π, what is the height of the cone when the radius is 12?

Answers

Answer 1

Answer:

16units

Step-by-step explanation:

Given data

The expression for the volume of a cone is given as

v=1/3πr^2h

v= 3π

r= 12

h=???

Substitute

3π= 1/3*π*12^2*h

3= 1/3*144*h

3= 144h/3

cross multiply

3*3= 144h

9= 144h

h= 144/9

h=16 units

Hence the heeight is 16units

Answers

Answer:

[tex] 10 \: { \: m}^{2} [/tex]

Step-by-step explanation:

area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m

[tex] = \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2} [/tex]

Answer:

shaded region = 10 m squared

Step-by-step explanation:

Area square = 6x6 = 36    Area reatangle 4x2 = 8

both areas = 44

Now lets subtract some white parts to obtain the shaded parts

1/2 of 4x6 = 12

1/2 of 6x6 = 18

1/2 of 4x2 =4

12+18+4= 34

44-34 = 10

When buying a candy bar, there is a 20% chance that it will also include a coupon for a second candy bar.

What is the value of BD

Answers

Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.

Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6

If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).

In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?

A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s

Answers

Answer:

C: 31 m/s

Step-by-step explanation:

It falls from a dam.

Thus;

Initial velocity; u = 0 m/s

Height; h = 49 m

Acceleration due to gravity is 9.8 m/s²

To solve for the final velocity this, we will use Newton's third equation of motion;

v² = u² + 2gh

v² = 0² + 2(9.8 × 49)

v = √960.5

v ≈ 31 m/s

An asteroid hit the earth and created a huge round crater. Scientists measured the distance around the crater as 26 miles. What is the area of the crater?

Answers

Answer:

53.8 mi^2

Step-by-step explanation:

First we need to determine the radius of the crater.  The circumfence formula is C = 2(pi)r, and here C = 26 miles.  Thus,

26 mi = 2(pi)r, so that

      26 mi

r = ------------ = 4.13 miles

        2pi

Then the area of the crater  is A = (pi)r^2, or:

A = 3.14(4.13 mi)^2 = 53.8 mi^2
