The answer is 769.3 cm²
The volume of the cylinder is : V = π r² h
<span>The ratio between the radius of the base and the height of the cylinder is 2:3:
r/h = 2/3
h = 3/2r
V = 1617 cm
</span>π = 3.14
1617 = πr² * 3/2 r
1617 = πr³ * 3/2
1617 * 2/3 = πr³
1078 = πr³
r³ = 1078/π = 1078/3.14 = 343
r = ∛343 = 7 cm
h = 3/2r = 3/2 * 7 = 10.5 cm
The surface area of the cylinder is:
SA = 2πr² + 2πrh
= 2 * 3.14 * 7² + 2 * 3.14 * 7 * 10.5
= 307.72 + 461.58
= 769.3 cm²
Y=5/2x
Or y=2.5x
Hope this helps
<h2>Answer:</h2>
3 ( x - 7 ) = 18
<h3>Explanation:</h3>
Let the number be x, so that
According to the Question,
The difference of a number and 7 will be x - 7
Then, three times the difference of a number and 7 is 18 will be 3 ( x - 7 ) = 18.
Answer:
300 feet below sea-level
Step-by-step explanation:
-212+36-88-36
