The area formula for a circle is \pi r^{2}.
So, if we know the diameter of the circle, we can divide the diameter by 2 to get <em>r</em> (radius).

A = \pi (8/2)^{2} = \pi (4)^2 = 16\pi inches squared.

Hope I could help you out!
Have a good one, and God bless you!

A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2

A quadratic function is defined by f(x) = 3x^2 + 4x - 2. A linear function is defined by g(x) = mx-5. What values of the slope o
irakobra [83]
You need to find points where the line g(x) intercepts the quadratic function f(x) in one and only one point.

Then 3x^2 + 4x -2 = mx - 5

solve 3x^2 + 4x - mx -2 + 5 = 0

3x^2 + (4 - m)x + 3 = 0

In order to there be only one solution (one intersection point) the radicand of the quadratic formula must be 0 =>

b^2 - 4ac = (4 - m)^2 - 4(3)(3) = 0

(4 - m)^2 = 24

4 - m = +/- √(24)

m = 4 +/- √(24) = 4 +/- 2√(6)

Then m, the slope of the line, may be 4 + 2√6 and 4 - 2√6

madam [21]
We know that

Jayden cleans 12 rooms in---------------> <span>6 hours
 X rooms-------------------------------------> 4 hours
X=4*12/6--------> 48/6---------> 8 rooms
that means  </span>Jayden  cleans in 4 hours 8 rooms

Chandra cleans 12 rooms in---------------> 12 hours
 X rooms-------------------------------------> 4 hours
X=4*12/12--------> 48/12---------> 4 rooms
that means Chandra  cleans in 4 hours 4 rooms

the answer is
<span>Jayden = 8 blankrooms
</span><span>Chandra = 4 blankrooms</span>
