why does the formula for area of a circle make sense

Answers

Answer:

Step-by-step explanation:

The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

For a spherical object to just barely block the sun from your view, the ratio of the
length of the object's conical shadow, measured from the object to your eye, to
the object's diameter must be about 108: 1. How far in feet from your eye would a

Answers

The tennis ball's distance from the eye can be determined by using similar triangles.

The distance of the tennis ball from the eye to block out the Sun is; 24.3 feet.

Reasons:

The given parameter are;

The ratio of the shadow to the objects diameter = 108 : 1

[tex]\dfrac{108}{1} = \dfrac{Distance \ of \ tennis \ ball}{2.7}[/tex]

The distance of the tennis ball from the eye = 108 × 2.7 in. = 291.6 in.

291.6 inches = 24.3 feet

The distance of the tennis ball from the eye to block out the Sun is 24.3 feet.

mark owes his sister $15.he earned $20 for mowing the grass. he gave 1/5 of his warning to a local charity and then paid his sister. does mark have enough to repay his sister the full amount?

Answers

Answer:

Yes, with some change to spare.

Step-by-step explanation:

He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

what is the slope of the line // will give lots of points and brainliest

Answers

m= 1/2. for slope always think “rise/run” as a fraction for when you hit the next point. up/down x amount divided by left/right x amount

Answer:

  1/2

Step-by-step explanation:

It usually works well to compute the slope from coordinates where the graph crosses grid line intersections. We can identify two of those as ...

  (-1, 3) and (1, 4)

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -3)/(1 -(-1)) = 1/2

The slope of the line is 1/2.

Additional comment

The y-intercept is 3 1/2.

An equation for the line could be ...

  y = 1/2x + 3 1/2 . . . slope-intercept form

Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels  18  miles per hour slower than the eastbound train. If the two trains are  300  miles apart after  2  hours, what is the rate of the westbound train? Do not do any rounding.​

Answers

Answer:

66 mph

Step-by-step explanation:

w = e - 18

2w + 2e = 300

2 (e - 18) + 2e = 300

2e - 36 + 2e = 300

4e - 36 = 300

4e = 300 + 36 = 336

e = 84 mph

w = 66 mph

The westbound train is travelling at 66 mph

Answers

Answer:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Step-by-step explanation:

1. The Fibonacci sequence states that each number is the sum of the two numbers before it.

For example, if we have the first two numbers of a sequence as 5 then 6, the next term would be 11.

2. Given the information above, let's solve the question.

-> A: 9 + 14 = 23, 14 + 23 = 37

The next two terms for sequence A are 23 then 37

-> B: 10 + 16 = 26, 16 + 26 = 42

The next two terms for sequence B are 26 then 42

Therefore, the answer is:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42
