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:

Step-by-step explanation:



Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.




The answer should be without negative exponents.


Hj and jk are the same length line segments ( because the midpoint divides a line into two equal parts)
So hj = jk.
hk is the line segment which has the mid point j. It is the double of hj or jk. It can be the sum of hj and jk.
hj + jk = hk
or
2 * hj = hk
or
2 * jk = hk
Since each towel costs the same amount, you need to divide the total cost by the amount purchased. t = $39.60/8 towels. Solved, your answer would be t = $4.95 per towel.
A ratio is like say there are 25 boys as to 23 girls or its a comparison in the number of things of different objects or like for every 2 cats there 1 dog
