Answer:
B (the second choice)
Step-by-step explanation:
to calculate the area of a circle you use the formula A= π r²
the radius of the circle is 5 in, so the only answer that could work is
π(5in)²(30/360).
Hope this helps <3

Answer:
Solar constant - Heat flux density.
Step-by-step explanation:
The solar constant (GSC) is a flux density measuring mean solar electromagnetic radiation (solar irradiance) per unit area. It is also defined as the rate at which solar radiation is received on a unit surface that is perpendicular to the direction of incident radiation just outside Earth's atmosphere at Earth's mean distance from the Sun; equal to 2 cal/cm^2.min.

Step-by-step explanation:
Answer:
Value is x=8 and y=4
Step-by-step explanation:
Given : A right triangle 'A' hypotenuse length of x+4 and a leg of x,
and right triangle 'B' hypotenuse length of 3y and a leg length of y+4
To find : For what values of x and y are the triangles congruent by HL?
Solution :
Triangle A,
Hypotenuse: x+4
Leg: x
Triangle B,
Hypotenuse: 3y
Leg: y+4
Since the triangle A and B are congruent so, the sides of triangles are equal.
(Hypotenuse are equal) ..........[1]
and
(Legs are equal) ..........[2]
Solving the equation of system,
Put the value of x from [2] in [1],
![x+4=3y](https://tex.z-dn.net/?f=x%2B4%3D3y)
![y+4+4=3y](https://tex.z-dn.net/?f=y%2B4%2B4%3D3y)
![8=2y](https://tex.z-dn.net/?f=8%3D2y)
![y=4](https://tex.z-dn.net/?f=y%3D4)
Substitute y in [2],
Therefore, The value of x=8 and y=4
Verifying for the values of x and y:
Triangle A,
Hypotenuse: x+4=8+4=12
Leg: x=8
Triangle B,
Hypotenuse: 3y=3(4)=12
Leg: y+4=4+4=8
Both hypotenuses and both legs are equal hence they are congruent.
