Answer:

50.24

And, you're not bad at math! You goot this correct! :)

Step-by-step explanation:

c=25.12

we can use this to find the raidus!

plug it back into the circumference formula first.

c=(pi)(d)

25.12=3.14*d

divide both sides by 3.14!

d=8 but we need the radius, so we just divide by 2. 8/2 = 4. so the raidus is 4!

now we plug it into the area of a circle formula.

π · r2

3.14 * 4^2

3.14*16

50.24

Your hourly salary increased from $15 to $22 what is the precent increase in your salary?

Elanso [62]

The percentage increase is 46%.

Original number/start = $15

End number = $22

Increase = $22 - $15 = $7

% increase = Increase ÷ Original Number × 100

Substitute in known values

% increase = 7 ÷ 15 × 100

Divide

% increase = 0.46 × 100

Multiply

% increase = 46%

The percentage increase is 46%.

The midpoint of AB is M (2,0). If the coordinates of A are, (-3, 3), what are the coordinates of B?

gregori [183]

Given:

M is the midpoint of AB.

M(2,0) and A(-3, 3).

To find:

The coordinates of point B.

Solution:

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get

$(2,0)=\left(\dfrac{-3+a}{2},\dfrac{3+b}{2}\right)$

On comparing both sides, we get

$\dfrac{-3+a}{2}=2$

$-3+a=2\times 2$

$a=4+3$

$a=7$

And,

$\dfrac{3+b}{2}=0$

$3+b=0$

$3+b-3=0-3$

$b=-3$

Therefore, the coordinates of point B are (7,-3).
