Answer:
15
Step-by-step explanation:
The arc length of the semicircle is 15.7
<h3>Calculating Arc length </h3>
From the question, we are to determine the arc length of the semicircle
Arc length can be determined by using the formula,
Arc length = θ/360° × 2πr
Where θ is the angle subtended by the arc
and r is the radius of the circle
In the given diagram,
θ = 180°
and r = 10/2
r = 5
Thus,
The arc length of the semicircle = 180°/360° ×2×3.14×5
The arc length of the semicircle = 1/2×2×3.14×5
The arc length of the semicircle = 15.7
Hence, the arc length of the semicircle is 15.7

Answer:
358 in²
Step-by-step explanation:
Length = 7
Width = 5
Height = 12
Thank my friend Sabrina for telling me the length, width, and height lol.
Then you plug the values in:
2(7x5) + 2(7x12) + 2(5x12)=358
We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)
the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²
see the attached figure
