The figure is made up of a cylinder and 2 cones. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neare

st hundredth.
Please help!!!!!
A cylinder and 2 cones. All have a radius of 2 millimeters. The cones have heights of 4 millimeters and 2 millimeters, and the cylinder has a height of 5 millimeters.

Recall the formulas V = B h and V = one-third B h

Answer:

96.29  mm^3

Step-by-step explanation:

Cylinder

V = pi r^2 h

V = 3.14 ( 2)^2 ( 5)

V = 3.14 *4*5

V =62.8 mm^3

Cone

V = 1/3 pi r^2 h

V = 1/3 (3.14) 2^2 ( 4)

V =1/3 (3.14) 4*4

V =16.746666666 mm^3

There are 2 cones so multiply by 2

Both cones = 33.493333333333 mm ^3

Add the cones and the cylinder together

62.8+33.493333333 =96.293333333

Rounding to the nearest hundredth

96.29  mm^3

Start with the equation 5 • 0 = 0 to explain why 5 • -2 must equal -10. Drag descriptions and equations to the table to complete
lorasvet [3.4K]

Answer:



Step-by-step explanation:

1. The problem is telling us to start with the equation 5*0=0

2. Substitute. Any number plus its opposite is zero. Since the opposite of 10 is -10, 10+(-10)= 0:  5(10+-10)=0

3. 3 Use the distributive property. In other words multiply 5 by 10 and 5 by -10: 4·10+5·-10=0

4. Multiply. perform the first multiplication of step 4: 5·10=50, so: 50+4·-10=0

5. Subtract 50 from both sides. 50-50+5·-10=0-50; simplify the left side: 0+5·-10=0-40

5·-10=0-50

6. Simplify to solve for 5·-10. Simplify the right side: 5·-10=-50

____________________________________________________________

Given.  5·0=0

Step 2 Substitute. Any number plus its opposite is zero.   5(10+-10)=0

Step 3 Use the distributive property.    5·10+5·-10=0

Step 4 Multiply. 40+4·-10=0

Step 5 Subtract 40 from both sides.    5·-10=0-50

Step 5 Simplify to solve for 4·-10.        5·-10=-50

Step two:Then use π which is 3.14

Step three:Multiply 5.5*3.14 which gives you 17.27 round to the nearest tenth would be 17.28

What is the minimum or maximum value of the equation of this equation?<br> f(x) = -(x-8)^2 -30​
Snezhnost [94]

9514 1404 393

Answer:

  f(8) = -30 is the maximum

Step-by-step explanation:

The equation is that of a parabola in vertex form:

  y = a(x -h)^2 +k . . . . . . . . (h, k) is the vertex; 'a' is the scale factor

Comparing this form to the given equation, we have ...

  f(x) = -(x -8)^2 -30

  • a = -1
  • h = 8
  • k = -30

That is, the scale factor is -1, and the vertex is (8, -30).

When the scale factor is negative, the graph opens downward and the vertex is a maximum. The maximum value is -30.

Eunique scores 20 points during the game. This is eleven more than three-fifths of the points she scored in previous game. How m
Ket [755]

Answer:

Step-by-step explanation:

If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said.  20=11+(3/5)x.  Hopefully that makes sense.  3/5 of the previous score plus 11 is 20.  Anyway, you can just solve this algebraic expression for x.

20=11+(3/5)x subtract 11 from both sides

9 = 3/5 x Multiply both sides by 5

45 = 3x then divide both sides by 3

15 = x And there you go.
