Answer: C≈62.83ft

Step-by-step explanation:

simply take your radius and times it by 2 and you get 20. then times twenty by pi.

Approximate circumference of circle is $20\pi$ feet that is 62.8 feet.

Solution :

Need to determine approximate circumference of a circle with radius as 10 feet.

So given that radius of circle = 10 feet

Circumference of circle is product of constant $2\pi$ with radius of circle r.

=> Circumference of circle = $2\pi r$

On substituting the value of radius, we get circumference

So circumference of a circle of radius 10 feet = $2\pi \times 10 = 20\pi$

Taking $\pi$ = 3.14, we get circumference = 20 x 3.14 = 62.8 feet

Hence approximate circumference of circle is $20\pi$ feet that is 62.8 feet.

The base of a triangle is twelvetwelve more than twice its height. if the area of the triangle is 4545 square centimeters, find

mr Goodwill [35]

In order to begin we must start off with the formula for the area of a triangle, which is a=1/2b(h) where a is area, b is base, and h is height.

In this scenario, we know that the area is 45cm^2 and the base is 2h+12 (since it is twice it’s height plus twelve). We can plug this into the area equation and then proceed to solve out accordingly.
a=1/2b(h)
45=1/2(2h+12)(h)
90=(2h+12)(h)
90=2h^2 + 12h
0= 2h^2 + 12h - 90

Simplify by dividing the two out.

h^2 + 6h - 45 = 0.

Now plug into the quadratic formula (with a=1, b=6, and c=-45) as shown in the image below.

After plugging the equation in and solving, we come to the idea that h is roughly equal to 4.34. We can now plug this back into the triangle area formula to solve out for b.
a=1/2b(h)
45=1/2(2h + 12)(h)
45=1/2(20.69)(4.34)
45=45.

In conclusion;
The height is ≈ 4.34
The base is ≈ 8.68

Hope this helps :)

If line L is parallel to line K, then they

ddd [48]

An equivalent statement will be if lines L and K intersect, then they are not parallel.

<h3>Parallel lines</h3>

Parallel lines are lines that do not meet. The angle between the parallel lines is 0 degrees

The statement if line L is parallel to line K, then they will never intersect is true and an equivalent statement will be if lines L and K intersect, then they are not parallel.

This is determined using the contrapositive statements

1. You are rolling a pair of dice. What's the probability of getting different numbers on both dice?

GaryK [48]

Answer:

Step-by-step explanation:

Total outcomes:

6*6 = 36

Outcomes with same numbers on both dice:

Outcomes with different numbers on both dice:

36 - 6 = 30

Probability of different numbers on both dice:

30/36 = 5/6

stira [4]

Answer:

Nope

Step-by-step explanation:

If it is a square garden, all sides are equal. Area would be 17x17 and that would equal $289^{2} ft$ not 34
