Answer:
Step-by-step explanation:
The formula for the length of an arc is s = rФ.
Thus, the arc length of a semicircle is S = rФ/2.
Here the radius is 5 (half the diameter), and so in this case the arc length is
S = (5 units)π/2, or S = (5/2)(3.14) units, or approximately S = 7.85 units
Its important to know math inn life helps you with lots of skills like science does

Answer:
The volume of a prism on its own = 248.5cm^3
The volume of a cylinder = 87.92cm^3
Step-by-step explanation:
The volume does not change for the prism as the hole was drilled.
We can show the drilled space with v(l) and (p) for prism V
v(l) 248.5p - 87.92p + 87.92p
= 248.5p
