Answer:
8.20in³
Step-by-step explanation:
Given V = πr²h
r is the radius = 1.5in
h is the height = 6in
thickness of wall of the cylinder dr = 0.04in
top and bottom thickness dh 0.07in+0.07in = 0.14in
To compute the volume, we will find the value of dV
dV = dV/dr • dr + dV/dh • dh
dV/dr = 2πrh
dV/dh = πr²
dV = 2πrh dr + πr² dh
Substituting the values into the formula
dV = 2π(1.5)(6)•(0.04) + π(1.5)²(6) • 0.14
dV = 2π (0.36)+π(1.89)
dV = 0.72π+1.89π
dV = 2.61π
dV = 2.61(3.14)
dV = 8.1954in³
Hence volume, in cubic inches, of metal in the walls and top and bottom of the can is 8.20in³ (to two dp)
Answer:
<h2>See below</h2>
Step-by-step explanation:
For every odd place, the first one, the third one, and so on, the rule to increase each number by 2 then 3 then 5. This is because every even numbered digit, shows how much to increase the other digits by, minus one at the beginning, no change in the middle, and plus one at the end.
I'm always happy to help :)
The slope would be 3/4 because 5 - 2 is 3 and -1 - (-5) is 4. Hope this helps!
Answer:
c = 1.5 d
Step-by-step explanation:
cost of 4 small drinks = $6
cost of 1 small drink = $
= $1.5
cost of d small drinks = 1.5 d = c
∴ c = 1.5 d
