Answer:
15.35 m²
Step-by-step explanation:
For a central angle of θ in radians, the area of a segment is ...
A = (1/2)r²(θ -sin(θ))
The central angle subtending the segment is 120°, or 2π/3 radians. Thus the segment area is ...
A = (1/2)(5 m)²(2π/3 -sin(2π/3)) = (25 m²)(π/3 -(√3)/4)
A ≈ 15.35 m² . . . . area of shaded segment
Answer:
you multiply 2y x 2y x 2y x 2y x 2y x 2y
Step-by-step explanation:
Answer:
They are not similar.
Step-by-step explanation:
To find whether or not they are similar, set them up as a proportion.
(2.4/5.2) = (8/13)
Now cross multiply.
2.4*13 = 5.2*8
31.2 = 41.6
Since they are not exact, they are not similar.
8/14 boys, 6/14 girls which means 4/7 boys and 3/7 girls
In order to solve this, you have to plug in all of the costs of the gifts and add them, which in all equals $36. since jim only has 1/4 of the money he needs to buy the gifts, you need to divide 36 by 4. this gives you 9, so now you know he has 9 dollars.
and to find out how much more money he needs, you can subtract 9 from 36 which represents a fourth of the required money. the answer is 27, that's how much jim needs in order to buy his gifts.
