Answer:
They will need to hire 5 testers.
Step-by-step explanation:
This question can be solved using a simple rule of three.
For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?
10 developers - 2.5 testers
20 developers - x testes




They will need to hire 5 testers.
Answer:
113.04
Step-by-step explanation:
Radius(r)= 4/2 = 2
Volume = r² x π x h
⇒ 4 x 3.14 x 9 = 113.04 (when using pi = 3.14)

Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
.2+3.6=3.8 because all you do is add the .2 feet with 3.6 feet
