Answer:
A≈12.57
r Radius 2
Step-by-step explanation:
★ QUADRATIC RESOLUTION ★
Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions
D < 0
b² - 4ac < 0
4² - 4 ( 5 ) < 0
16 - 20 < 0
-4 < 0
Hence it's character is stated above

Answer: The one that ends in +14
Step-by-step explanation:
Answer:
The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3
Step-by-step explanation:
Formula:
V=πr^2h
radius=2
height=15
V=π(2)^2*15
π(4)*15
4*15=60
60π
π=3.14
60(3.14)
188.4
Since its volume you have to cube it
188.4 cm^3
