What is the exact circumference of a circle with a radius of 15 cm? 10πcm 15πcm 30πcm 60πcm WIIL GIVE BRAINLIEST

Answers

Answer:

(C) 30πcm

Step-by-step explanation:

In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.

Answer:

37 pi

Step-by-step explanation:

The circumference of a circle is equal to pi times the diameter.

The formula for the circumference of a circle is C=pi d,and since d = 37 ,we know that C=37 pi.

37 pi =116.238928183,but pi is irrational and the decimal will never end.

Thus,the most exact way to express the circumference is 37 pi.

What is Area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.

We have, Radius of semicircle = 2 in

So, Area of semicircle = πr²/2

                                    = 3.14/2 x 2/2 x 2 /2

                                    = 1.57 x 1 x 1

                                    = 1.57 mm²

So, the area of the semicircle is 1.57 mm².

Therefore, Radius = 1 in

Which is a solution to 2x + 1 = 21?

Answers

Answer:

x = 10 is your answer

- Explain -

Step 1: subtract 1 from both sides (subtraction of equality)

which will give us:

2x = 21 - 1

which equals to

2x = 20

Step 2: Divide both sides by 2

which is

2x/2 = 20/2

2/2 = 1 and 20/2 = 10

Therefore the answer is x = 10

What value of a makes the equation true

Answers

Answer:

The correct answer is -2.

Step-by-step explanation:

it is -2 because if you replaced -2 with a you would have -2 minus 1.5 which is -0.5. -0.5 multiplied by 3 gets you -1.5.

Answer:

Step-by-step explanation:

3(a + 1.5) = -1.5

3a + 3*1.5 = -1.5

3a + 4.5 = -1.5

Subtract 4.5 from both sides

3a + 4.5 - 4.5 = -1.5 - 4.5

3a +0 = - 6.0

3a = - 6

Divide both sides by 3

3a/3 = -6/3

a = -2

To solve this equation I used the quadratic formula.

1. Place the units into the following formula. -b+-sqrtb^2-4ac

                                                                                  2a

2. After placing the units into the formula it should be -1+-sqrt1+24

                                                                                                   2

3. This should leave you with two possible answers -3 and 2 after solving it. The answer can not be negative of course cause there is no such thing as a negative time. So the answer has to be 2.

Step-by-step explanation:

The type of function is Quadratic.

What is function?

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

x  0    1    2       3     4      5

y  - 1  0    - 3    - 10   - 21   - 36

As, we can see from the table ,

The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.

However, the second differences are all equal to -4, which indicates that the function has a quadratic form.

Hence, the function is quadratic.

Answers

Answer:

Step-by-step explanation:

Suppose h is the inverse of f then

f(x) = y ⇔ h(y) = x

f(x) = y ⇔ 4x = y ⇔ x = y/4

and since x = h(y) then h(y) = y/4

then we can write :
