Answer:
so if we make a pie chart
there's 25 marbles
it'll be 1/25 or 4% chance
a red marble is 5/ 25 or a 20% chance
say if you replace the white on the chances of you getting red will be 24% or 6/25 chance of getting red
Answer:
Step-by-step explanation:
Let x is the length of the square side.
We know: the two figures have the same area
<=>
= π
(r being radius)
<=> x =
r
perimeter square = 4x = 4*r*
perimeter circle = 2*r*π
<=> 390 = 4*r*
+ 2*r*π
<=> r = 29.16
=> perimeter square = 4*29.16*π
=> perimeter circle = 58.32π

Answer:

Step-by-step explanation:
Shown is one-fourth of a circle. Also, according to the picture, the radius is 28 meters.
The area for a whole circle is
.
Using that information, we can find the area as if the circle was whole instead of just the fourth.

Now that we know the area of the whole circle, we just have to divide it by four to find the area of the fourth of the circle.

That means that the area of the shape shown is
.
I hope this helps!
