The circumference of a circle is 100.48 meters. What is the circle's radius?
Use 3.14 for pi

Answer:

176 cm

Step-by-step explanation:

Area of a triangle = h b/2

8 * 11 ÷ 2 = 44 cm

Area of a rectangle = l * w

12 * 11 = 132 cm

Add both areas together

44 + 132 = 176 cm

Answer:

720in

Step-by-step explanation:

V=LWH

V=(18)(4)(10)

Answer:

720

Step-by-step explanation:

Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².

π≈3.14

A. C=πd

Simply plug in the numbers into the formula.

Diameter=Radius*2

17*2=34

C=34(π)

B. (π)(5²)

Plug in the numbers into the formula. Remember that half of the diameter is the radius.

C.  (π)(4.5)

There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.

The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.

D. (π)(6.5²)

Remember that the formula for calculating the area of a circle is πr².

Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.

(π)(6.5²)

Therefore, the last answer choice is the correct answer.

Answer:

a = 93°, b = 120°, c = 150°

Step-by-step explanation:

b + 36 = 78 × 2 => b + 36 = 156 => b = 120°

87 × 2 - b = the minor arc between a and 78

=> 174 - 120 = 54

54 + b + 36 + c = 360

=> 54 + 120 + 36 + c = 360

=> c = 150°

(c + 36) ÷ 2 = a

=> (150 + 36) ÷ 2 = a

=> a = 93°

Answer:

b=2

Step-by-step explanation:

To get slope given two points, take the difference of the y values and divide it by the difference of the x values.

(This is also called change in y over change in x, or rise over run)

b-(-2)/2-1=4

b+2/1=4

b+2=4

b=2

Answer:  B: 0.81 miles

Step-by-step explanation:

The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

The formula for this is: a^2 + b^2 = c^2

So let the first side or a be .19

and the second side be .28

and now we are looking for c which is the missing side

.19^2 + .28^2 = c^20.0361 + 0.784 = .1145

get the square root of .1145

√.1145 = it is approximately 0.34

get the total distance by adding three sides

= .34 + .19 + .28

= 0.81

Answer:

0.68

Step-by-step explanation:

you got to multiply

Answer: 60

8x15 / 2

Step-by-step explanation:

Answer:

40 units

Step-by-step explanation:

Using Pythagoras Theorem to find the hypotenuse:

[tex] \sqrt{ {15}^{2} + {8}^{2} } [/tex]

[tex] = \sqrt{289} [/tex]

= 17 units

The perimeter

= 15+8+17

= 40 units

Answer:

6/7

Step-by-step explanation:

The constant rate of change is also know as the slope of the expression

Given

24x-28y=14

Write in standard form y = mx+c

m is the slope

24x-28y=14

-28y = -24x + 14

y = -24x/-28 + 14/-28

y = 6/7 x - 1/2

Compare

mx = 6/7 x

m = 6/7

Hence the  constant rate of change is 6/7

Answer:

Answer:

-11

Step-by-step explanation:

Simply plug in a=-3 and b=2 into the equation provided. Remember the signs (+/-) and be careful with your calculations.

-(-3) - (2)^3 + (-3)(2)  = -11

Answer:

1680.

Step-by-step explanation:

30 * 56

Answer:

40

Step-by-step explanation:

The two angles form a right angle

A right angle has a measure of 90 degrees meaning that the sum of the two angles is 90

a + 50 = 90

90 - 50 = 40

Thus, a = 40

missing angle is (40⁰) :)

Answer:

C. Zero

Step-by-step explanation:

The solution of the system of equations would be the point where they intersect, but since these lines are parallel, they will never intersect, so therefore there are zero solutions.

Answer:

5n+4

Step-by-step explanation:

Four more than 5 times a number (n)

So we get 5n+4

Answer:

5n+4

Step-by-step explanation:

As you have 4 more, you know you need to add four to n. Then, the expression asks 5 times n, leaving 5n+4.

Answer: 1,127 km.

Disclaimer: There are a plethora of ways to solve this problem, but I decided to utilize proportions to solve it, as I believe that it is the easiest method to solve these types of questions.

1. Set up your proportion

2. Set up a basic algebraic equation: 1x=700

In other words, what times 1 is 700?

Multiply 1*700, which is 700, and do the same for the bottom.

1.61*700= 1,127

3. The final answer is 1,127 kilometers. Please refer to the pictures attached for a more visual and thorough explanation. Cross mutiplying could also be used. Simply cross multiply in your proportion to get your answer.

Answer:

Hello again! x = 85

Step-by-step explanation:

Because triangles are 180 degrees and

68 + 27 = 95 and 180 - 95 = 85 so our missing angle is 85 hope this helps!

Answer:

Answer:

C. 12

Step-by-step explanation:

Find the percentage of him drawing a blue marble.

4/10 = 0.4

He has a 40% chance of picking blue.

Find 40% of 30.

12

He would draw a blue marble around 12 times.

Answer:

C

Explanation:

So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:

4/10

Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:

12/30

So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....

Hope this helps!
