Answer:
(-2, 11/2)
Step-by-step explanation:
use the mid-point formula!
((x1+x2)/2, (y1+y2)/2)
((-1+-3)/2, (-1+12)/2)
(-2, 11/2)
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³
Answer:
x = 7
Step-by-step explanation:
3x²+5=152
3x²=147
x²=147/3
x² = 49
x = 7
