It's -5/2,-4 is right. ok?
Answer:
h = 
- r
Step-by-step explanation:
The question requires you to make h the subject of the formula.
S = 2πrh + 2πr²
subtract 2πr² on both sides.
S - 2πr² = 2πrh - 2πr² - 2πr²
S - 2πr² = 2πrh
Dividing both sides by 2πr
(S - 2πr²)/2πr = 2πrh/ 2πr
h = - r
Answer:
277cm²
Step-by-step explanation:
Base = 9x8=72
There are 2 triangles with a bottom edge of 9 and a slant height of 13:
1/2(9)(13)=58.5
There are 2 triangles with a bottom edge of 8 and a slant height of 11:
1/2(8)(11)=44
72+58.5+58.5+44+44=277cm²
-0.83 for it’s the lowest number
Answer:
3/7
Step-by-step explanation:
There are 7 letters in ALABAMA. And there are 4 A's in ALABAMA. So if you're trying to not get an A then you would subtract 4 from 7. Which you would get 3/7 of the letters in ALABAMA are not A.
