The surface area of a ball is 3,600 square millimeters. What is the balls radius

1 answer:

4 0

$A = 4 \pi r^2$

$3600 = 4\pi r^2$

$\dfrac{3600}{4 \pi} = r^2$

$r^2 = 286.479$

$r = 16.9$

Answer: The radius is 16.9 mm.

Answer:

C.

Step-by-step explanation:

I already used this example but...

Converse. Switching the hypothesis and conclusion of a conditional statement. For example, the converse of "If it is raining then the grass is wet" is "If the grass is wet then it is raining."

Note: As in the example, a proposition may be true but have a false converse.

It has to have the same meaning, but in a different format, so the only answer that follows this rule is C.

Hope this helps, have a good day. c;

Answer: C) y ≥ 3x - 2; $y\leq \dfrac{1}{2}x+3$

Step-by-step explanation:

Blue line:

y-intercept (b) = -2

slope (m) is 3 up, 1 right = 3

shading is above

⇒ y ≥ 3x - 2

Yellow line:

y-intercept (b) = 3

slope (m) is 1 up, 2 right = $\dfrac{1}{2}$

shading is below

$\implies \bold{y\leq \dfrac{1}{2}x+3}$

Find the value of x that makes lines u and v parallel

gogolik [260]

Answer:

x = 4 for Lines U and V to be parallel

Skills needed: HS Geo, Angle Theorems, Equations

Step-by-step explanation:

1) We see that there are two angle measures given to us. There is an angle marked with the measure of $130$ °, and the other is marked with ( $33x-2$ )°.

First of all, these two angles are categorized alternate interior angles. They are on alternate sides of the transversal, and are within the two lines (not on the outer side of the lines). I will add an image for reference regarding this idea.
If 2 lines are parallel, alternate interior angles are congruent. This means that: $33x-2=130$
