Answer:
Volume of a cylinder = πr²h
Given
V=81π
r=3
find h
Making h the subject
h= V/πr² = 81π/π(3)²
h= 81/9
h= 9cm
Answer:
D. 101
Step-by-step explanation:
(25x+1)+(25x-2)+(20x-1)+82=360
70x=360-1+2+1-82
70x=280
x=4
A=25x+1=101
Answer:
1.8% or 1.818181%
Step-by-step explanation:
If in a batch of 440 water purifiers, we find 8 to be defective.
Then the probability of the next purifier being defective is 8/440
In percentage = 8/440 * 100
=> 8/44 * 10
=> 8/22 * 5
=> 40/22
=> 20 / 11
20/11 is roughly 1.8181818
Rounding it to the nearest tenth, we get 1.8%
