Answer:
12.5 pi or 39.26990
Step-by-step explanation:
First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:
We can substitute what we have:
This gives us:
12.5 pi or 39.26990(Not sure what format you need it in)

Answer:
5/11
Step-by-step explanation:
Answer:
y = 3x -31
Step-by-step explanation:
y=mx+b
m=3
5 = 3*12 +b
b = 5 - 36
b = -31
y = 3x -31
Answer:
179.3 square units
Step-by-step explanation:
The area of the figure is the sum of the areas of the parts. That is, the area is the sum of the area of the rectangle, and the area of the semicircle.
__
<h3>Semicircle</h3>
The area of a circle with radius 5 is ...
A = πr²
A = π(5²) = 25π
The area of the semicircle is half that:
semicircle area = (25π)/2 = 12.5π ≈ 39.3 . . . . square units
<h3>Rectangle</h3>
The area of a rectangle with length L and width W is ...
A = LW
The width of this rectangle is the diameter of the circle, twice the radius, or 10 units.
A = (14)(10) = 140 . . . . square units
<h3>Total area</h3>
The sum of the areas of the parts is ...
total area = semicircle area + rectangle area
total area = 39.3 + 140 = 179.3 . . . . square units
