First you need to find the area of the whole circle.

The radius is given as 10, so just insert 10 into the equation of the area of a circle equation.

Putting

after the 100 because that is what is commonly done.
Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections.
Since the area of the whole circle is

then we just divide that by 4,
leaving us with 25

and that is our final answer
Answer:
its 23
Step-by-step explanation:
its 12+11 because two negatives make a positive
Answer:
1/18
Step-by-step explanation:
The probability of rolling a 1 is 1/6 because there are 6 numbers. You multiply that probability by the probability of getting a 2 or 3 which is 2/6 or 1/3 to get 1/18.
