c one is the correct answer
Answer:
2770.9 in³
Step-by-step explanation:
A cylinder has a base radius of 7in and a height of 18in. What is its volume in cubic inch to the nearest tenths place?
The formula for the volume of a cylinder is given as:
πr²h
r = radius = 7 in
h = height = 18 in
Hence:
Volume of the cylinder = π × 7² × 18
= 2770.88472 in³
Approximately to the nearest tenth = 2770.9 in³
Answer: 18/5
Step-by-step explanation:5x3=15/5 + 3/5=18/5
X+y=12
8x+10y=102
8x+8y=96
8x+10y=102 _
-2y= -6
y=3
x+y=12
x=12- 3
x=9
or
8x+10y=102
8x+30=102
8x=102-30
8x=72
x=9
