C=πd
58π=πd
We conclude that
d=58 cm
r=1/2d
r=58(1/2)
r=29 cm
A=πr^2
A=29^2π
A=841π
Or
A≈2640.74 square cm. Hope it help!

Which graph represents the solution to the given system? y = –2x + 5 and y = 3x – 2
DaniilM [7]
Y = -2x + 5        y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2             Subtract 3x from both sides
-5x + 5 = -2                  Subtract 5 from both sides
-5x = -7                        Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)

What is the greatest common factor of 16 and 40?
myrzilka [38]

Answer:

<h3> 8 </h3>

Step-by-step explanation:

16 divided by 8 is 2. 40 divided by 8 is 5. Neither of these can be reduced by any more common numbers, so therefore, 8 is your greatest common factor. The GCF of 16 and 40 is 8.

Probability help!!!!!
nirvana33 [79]

Let A be the event A=\{choosing \;an \;odd \;number\} and B be the vent B=\{choosing \;an \;even \;number\}. Since the intersection of the events A\cap B=\phi, the events A and B are mutually exclusive.

The number is either odd or even. Since P(A)+P(B)=1, the events are mutually exclusive and exhaustive.

Correct choice is "the number is either odd or even".
