Answer: <u>105m²</u>
Formula for Area of Circle: A = π r²
so, A = 3.14 (6)² (I got 6 because radius is half the diameter)
Don't forget to divide the final area of the circle in half, because It's only a semicircle.
Formula for Triangle: A = ![\frac{bh}{2\\}](https://tex.z-dn.net/?f=%5Cfrac%7Bbh%7D%7B2%5C%5C%7D)
so, A =
(again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)
You need to multiply the final area of the triangle by 2 since there are 2 triangles.

Answer:
![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Step-by-step explanation:
We want probability that 1st is girl AND 2nd is girl as well.
In probability "AND" means multiplication and "OR" means "addition".
<u><em>We find the probabilities separately and multiply them together, since "AND".</em></u>
<u><em /></u>
- P(girl from 7th grader) = number of girl 7th grader/total number of 7th grader
=9/10
- P(girl from 8th grade) = number of girl in 8th grade/total number of 8th grader
=2/4
P(both girls) = 9/10 * 2/4 =9/20
