What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
A cylinder has surface area of 256 π square millimeters and a height of 8 millimeters.
Since, We know that;
Surface area of cylinder is,
SA = 2πrh + 2πr²
Here, We have;
SA = 256π
h = 8 mm
Hence, We get;
256π = 2π × r × 8 + 2π × r²
128 = 8r + r²
r² + 8r - 128 = 0
r² + 16r - 8r - 128 = 0
r (r + 16) - 8 (r + 16) = 0
(r - 8) (r + 16) = 0
r = 8 mm
Hence, The value of diameter is,
d = 2 x 8
d = 16 mm

The margin of error of 2.18 is 2.175 to 2.185.
Alina measured distance = 2.18 miles.
We need to find the margin of error of this measured distance.
What is the Margin of error?
The margin of error is the range of numbers where the original value is located in the middle of the range.
Half the smallestunit of the given number is used to find the marginoferror.
The given rounded number is 2.18.
The smallestunit of this number is 0.01.
0.01 / 2 = 0.005
We construct the margin of error as:
2.18 - 0.005 = 2.175
2.18 + 0.005 = 2.185
Thus, the margin of error of 2.18 is 2.175 to 2.185.

AnswEr :
Remember that, we usually take the error to be half of the smallest unit in a measurement
1. The error in this case = 1/2 x 0.01
=> 0.005
2. The minimum value = 2.18 - 0.005
=> 2.175
3. The maximum value = 2.18 + 0.005
=> 2.185
Therefore, the margin of error is 2.175 miles to 2.185 miles.

Step-by-step explanation:
Answer:
10e + 3 < 92
Step-by-step explanation:
Any number times ten plus three is less than 92. Like e = 3, which would be 10(3)+3, or 33. Any number that would make the statement true can be used in the place of e.

Note that the exact value of csc 60° with a rational denominator is (2√3)/3.
How to compute the above
The reciprocal identity states that csc(theta) = 1/sin(θ).
Since we know that sin 60 degrees = √3/2, we can substitute this value into the reciprocal identity -
csc 60° = 1/(√3/2).
To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator -
csc 60°= (1/(√3/2)) * (√3/√3).
csc 60° = √3/(√3 * (√3/2)).
= √3/(√3 * √3/2).
= √3/(√9/2).
= √3/(3/2).
To divide by a fraction, we multiply by its reciprocal -
csc 60° = √3 * (2/3).
csc 60° = (2√3)/3.
So it is correct to state that , the exact value of csc 60° with a rational denominator is (2√3)/3.
