Answer:
volume of a cylinder = 401.92cm³
Step-by-step explanation:
to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder
volume of a cylinder = πr²h
given that
height of the cylinder = 8cm
radius of the cylinder = 4cm
volume of a cylinder = π × (4cm)² × 8cm
volume of a cylinder = π × 16cm² × 8cm
volume of a cylinder = π128cm³
value of π = 3.14
volume of a cylinder = 3.14 × 128cm³
volume of a cylinder = 401.92cm³
Answer:
6
Step-by-step explanation:
4(6) - 7y = -18
24 - 7y = -18
-7y= -42
y= 6
First one is
(2x+5)
Second one is
“All of these are correct”
