The circumference of a circle is 18π, what is the radius?

Answers

Answer 1

Answer: 9

Explanation: Because pi is included in the answer, you won't be multiplying pi with it.
The only number that equals to 18 is 9.
By using the formula for circumference is: 2πr
2 x 9 = 18
Add pi, 18π.

If x and y vary inversely and x = -9 when y = -30, what is the constant of variation

Answers

Answer:

270

Step-by-step explanation:

 x = k/y     This is an inverse relationship with k = constant of proportion (or variation)

-9 = k/(-30)

k = -9  *  -30 = 270

Answer:

Constant of variation  = 270.

Step-by-step explanation:

y = k/x

-30 = k / -9

k = -30 * -9

k = 270

find the circumference and the area of a circle with 6m.
write your answer in terms of π, and be sure to include the correct units in your answer

Answers

Answer:

C = [tex]12\pi m[/tex]

A = [tex]36\pi m^2[/tex]

Step-by-step explanation:

I'm going to assume that the radius is 6m. The circumference of a circle is [tex]C = 2r\pi[/tex]. So we can plug in 6 for r and we get the circumference is [tex]12\pi m[/tex].

For area, the equation is [tex]A = \pi r^{2}[/tex]. So we can again plug in 6 for r and we get that the area is [tex]36\pi m^2[/tex].

If 6m is the diameter, then the circumference is [tex]6\pi m[/tex] and the area is [tex]9\pi m^2[/tex].

6 / 3√5

= 2√5/5

Answer:

 [tex]\frac{2\sqrt{5} }{5}[/tex]

Step-by-step explanation:

First, you can take a factor of (3) out of the numerator and denominator. This simplifies to equal 1, so you are left with 3/√5.

6 / 3√5   ----->   (3/3)  x  2/1√5  --->  (1)  x  2/√5  --->  2/√5

Because radicals should not be kept in the denominator, multiply both the numerator and denominator by the radical of 5. This removes the radical from the denominator while altering both the numerator and denominator equally. Remember, the square root of a number is technically the number raised to the 1/2 power. The 1/2 power times the 1/2 power equals the power of one, essentially "eliminating" the radical.

2/√5  --->  2/√5  x  √5/√5  --->  2√5 / 5

As there is not way to simplify further, your final answer should be [tex]\frac{2\sqrt{5} }{5}[/tex].

Joaquin is constructing the perpendicular bisector of ab. What should be his first step?
(100 points cuz why not)

Answers

Answer:

D. Open the compass so that the distance from the two points of the compass is wider than half the length of [tex]\over{AB}[/tex].

Step-by-step explanation:

To construct a perpendicular for [tex]\over{AB}[/tex], we must first take a compass & take the distance of its arms wider than half the length of [tex]\over{AB}[/tex].

This is done in order to get two intersecting arcs in the top & bottom of [tex]\over{AB}[/tex] so that a perpendicular bisector can be drawn through it.

After two intersecting lines are drawn below & above [tex]\over{AB}[/tex], draw a line joining these 2 points through their points of intersection. The point where it intersects [tex]\over{AB}[/tex] is the middle-most point of [tex]\over{AB}[/tex] & now a perpendicular bisector of [tex]\over{AB}[/tex] is constructed.
