The arc length of the semicircle is 5π units
<h3>Calculating length of an arc</h3>
From the question, we are to calculate the arc length of the semicircle
Arc length of a semicircle = 1/2 the circumference of the circle
∴ Arc length of a semicircle = 1/2 × 2πr
Arc length of a semicircle = πr
Where r is the radius
From the given information,
r = 5
∴ Arc length of the semicircle = 5 × π
Arc length of the semicircle = 5π units
Hence, the arc length of the semicircle is 5π units

Answer:
5 ways
Step-by-step explanation:
We have to name the cases.
1. 4 - 0 - 0 - 0
2. 3 - 1 - 0 - 0
3. 2 - 2 - 0 - 0
4. 2 - 1 - 1 - 0
5. 1 - 1 - 1 - 1
We don't name 0 - 0 - 1 - 3 or 0 - 1 - 1 - 2 etc. because it is the same thing.

Answer
Find out the what is the percentage of this discount .
To prove
Formula
Discount = Marked price - selling price
As given
a jar of natural peanut butter normally costs $4.00 .
it's on sale for $3.60 .
thus
Marked price = $4.00
selling price = $3.60
put in the above formula
Discount = 4.00 - 3.60
= 0.4
Formula
put the value
Discount percentage = 10%
Option (a) is correct .
Hence proved
54 as opposite angles are the same and they need to have the same angle to be parallel
