Answer:

The volume of a right circular cone that has a height of 16 m and a base with a  circumference of 14.7 m is 3,620.62 m³

Step-by-step explanation:

The right cone (or cone of revolution, or right circular cone) is the solid of revolution formed by rotating a right triangle around one of its legs. The bottom circle of the cone is called the base. That is, a cone is a three-dimensional figure with a circular base. A curved surface connects the base and the vertex.

The volume of a 3-dimensional solid is the amount of space it occupies.

The volume V of a cone with radius r is one-third the area of ​​the base B times the height h. This is:

[tex]V=\frac{1}{3}*A*h[/tex]

where A=π*r²

Then: V=[tex]\frac{1}{3}[/tex] *π*r²*h

In this case r=14.7 m and h=16 m. Replacing:

V=[tex]\frac{1}{3}[/tex] *π*(14.7 m)²*16 m

Solving, you get:

V=3,620.62 m³

The volume of a right circular cone that has a height of 16 m and a base with a  circumference of 14.7 m is 3,620.62 m³

Answer:

10cm^2

Step-by-step explanation:

The parallel sides of a parallelogram is 2cm apart

Their sum is 10cm

Therefore the area can be calculated as follows

= 2 ×10/2

= 20/2

= 10 cm^2

Hence the area is 10cm^2

Answer:

2340 degrees.

Step-by-step explanation:

The sum of the interior angle measures of any polygon can be calculated using the following expression ([tex]n[/tex] is the number of sides the polygon has):

[tex]180(n-2)[/tex]

For a 15-sided polygon, plug in 15 for n and simplify:

[tex]180(15-2)=180(13)[/tex]

Multiply to solve:

[tex]180(13)=2340[/tex]

For a 15-sided polygon, the sum of the interior angles must be 2340 degrees. You can go a step further and divide 2340 by 15 to figure out the individual measure of each interior angle (156 degrees).

The sum of the interior angles of a fifteen-sided polygon is 2340°.

The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

Given that, a fifteen-sided polygon.

Now, the sum of the interior angle measures is

(15-2)×180°

= 13×180°

= 2340°

Therefore, the sum of the interior angle measures is 2340°.

Answer:

Y=-1

Step-by-step explanation:

-4(y-2)

-4y+8=12

-8.       -8

-4y=4

-4.  -4

y=-1

Answer: Y = -1

Step-by-step explanation:

This is solved using the distributive property.

1. Distribute, so now it should look like -4y + 8 = 12

2. Now subtract the 8 from both sides to isolate -4y = 4

3. Divide -4 on both sides to get y = -1

Step-by-step explanation:

Amount of orange juice in 400ml glass

= 400ml * (40%/100%) = 160ml.

Amount of orange juice in 300ml glass

= 300ml * (1/2) = 150ml.

Since 150ml < 160ml, the 300ml glass contains less orange juice.

The second glass has less amount of orange juice.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Two glasses contain orange juice.

⇒ A 400ml glass is 40% full.

⇒ A 300ml glass is half full.

Now,

Since, Two glasses contain orange juice.

A 400ml glass is 40% full.

A 300ml glass is half full.

Hence, The amount of juice in first glass is,

⇒ 40% of 400

⇒ 40/100 × 400

⇒ 160 ml

And, The amount of juice in second glass is,

⇒ 300 / 2

⇒ 150 ml

Hence, The second glass has less amount of orange juice.

Answer:

y = -3/5x - 2

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)

Step-by-step explanation:

If you plug it into the pendulum formula given T = 2 π √(L/32), all you would have to do is set T=20 and solve for L

You would end up getting 3200/(π²)

Answer:

The number of pencils that needs to be placed at the other 1 inch end to get a balance again is approximately 3 pencils

Step-by-step explanation:

The given parameters are;

The length of the ruler used as a seesaw = 12 inch

The location where the pencil is placed = Under the 4 inch mark

The location where the weight is placed to balance the seesaw = The 2 inch mark

Therefore, the pencil at the 4 inch mark is fulcrum

The location where a pencil is placed on the ruler = The 12 inch end

The number of pencils, x, that needs to be placed at the other 1 inch end to get a balance again is given as follows;

The distance of the pencil at the 12 inch end from the fulcrum = 12 inches - 4 inches = 8 inches

The distance of the pencils placed at the 1 inch end from the fulcrum = 4 inches - 1 inch = 3 inches

Therefore at balance point, (equilibrium) the anticlockwise moment = The clockwise moment, which gives;

The mass of 1 pencil × 8 inches = x × The mass of 1 pencil × 3 inches

x = (The mass of 1 pencil × 8 inches)/(3 inches × The mass of x × 1 pencil)

x = 8/3 = 2.[tex]\overline 6[/tex]  ≈ 3 pencils

The number of pencils that needs to be placed at the other 1 inch end to get a balance again = x ≈ 3 pencils.
