Answer: 0.2
Answer:
P(1 and 2 are green) = 3/25
Step-by-step explanation:
We need to know the total number of marbles
6 Blue + 10 red + 9 green = 25 marbles
P ( 1st marble is green) = green/ total
= 9/25
Since we don't put it back, there are
6 Blue + 10 red + 8 green = 24 marbles
P ( 2st marble is green) = green/ total
= 8/24 = 1/3
P(1 and 2 are green) = P(1st green) * P(2nd green)
= 9/25 * 1/3
= 3/25
The answer is: "
122.65625 cm² " ; or, write as: "
122 cm² " .
________________________________________________________Note: ________________________________________________________The area, "A", of a circle:
A =
* r² ;
in which: A = area of the circle;
= 3.14 ;
r = radius ;
To calculate radius, "r" = diameter/2 = 12.5 cm/2 = 6.25 cm .
r = 6.25 cm ;
So, to calculate the area, "A" of the circle:
A =
* r² ;
Plug in the values to find the Area, "A" of the circle:
A = 3.14 * (6.25 cm)² ;
A = 3.14 * (6.25)² * cm² ;
A = 3.14 * 39.0625 * cm² ; Note that "39.0625" = "
" .
A =
122.65625 cm² ; or, write as: "
122 cm² " .
