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:
55.75
Step-by-step explanation:
find the area of 1 side using the base and height and divide that answer by 2
5x6=30     30 divided by 2=15
all sides are equal so each side is 15
the base you do the same thing.
base is 5, height is 4.3
4.3 x 5= 21.5
divide it by 2 10.75
side 1=15
side 2= 15
side 3=15
base 1= 10.75
add all together

Answer:
1: 8a²
2: 9a²b²c²
Step-by-step explanation:
1: 48a³ ÷ 6a
 48÷6 = 8
 8a²
2: 72a³b⁴c⁵ ÷ 8ab²c³
 72÷ 8 =9 
 9a²b²c²
