The answer is 3 ft
The surface area (SA) of a cylinder with radius r and height h is:
SA = 2πr² + 2πrh = π(2r² + 2rh)
We have:
SA = 126π ft²
h = 3 * d
d = 2r
h = 3 * 2r = 6r
126π = π(2r² + 2rh)
126 = 2r² + 2rh
126 = 2r² + 2r * 6r
126 = 2r² + 12r²
126 = 14r²
r² = 126/14
r² = 9
r = √9
r = 3
To get x intercept：
let y=0，x➖12=0，x=12
so x intercept point （12，0）
To get y intercept：
let x=0，3y➖12=0，y=4
so y intercept point （0，4）
1.847 rounds to 1.85 because the number in the thousandths place bumps it up since it is greater then 4. 1.798 rounds to 1.8 because the number in the thousandths place bumps the nine up to ten and you can't have a two digit number where there is only supposed to be one. so that "ten" bumps the 7 up to 8.
Answer: He does not have enough money
The pants are initially $40
1/4 of this is $10
40-10 = 30 is the discount price
Mr Jacobs is short $5 (since 30-25 = 5)
<span>40.4% I would say but if you need the whole problem I can give it to you.</span>
