Answer:
411.2 cm³
Step-by-step explanation:
for a cylinder, the volume V = πr²h
V = π x 4² x 12 = 411.2
X = 3 * 40 / 15 = 8
The answer is 8
Answer:
Step-by-step explanation:
x < 27°
The answer would be 5487/9 since it says each book has the same number of pages
Answer:
10 and -5
Step-by-step explanation:
x + y = 5
xy = -50
y = 5 - x
x(5-x) = -50
5x - x^2 = -50
x^2 - 5x - 50 = 0
from there on we can solve the classic way
Everything checks out.
