Answer:
C. 8,624
Step-by-step explanation:
recall that the formula for circumference is
Circumference = 2πr ( = given as 85 meters)
hence,
85 = 2πr
r = 85/(2π)
given h = 15m
volume of cylinder
= πr²h
= π (85/2π)² 15 (using calculator and assuming π = 3.14)
= 8628.58
Comparing with the choices, the closest choice (within rounding error) is C. 8,624
Answer: 4 1/10g^5+5 1/4
Step-by-step explanation:
Answer:
First, we have rounded numbers A and B, and we know that:
A + B = 11000
A - B = 3000
Now we can solve this system of equations as:
Isolating one variable in one of the equations, i will choose A in the second equation:
A = 3000 + B.
Now we can replace this into the other equation:
3000 + B + B = 11000
2*B = 11000 - 3000 = 8000
B = 8000/2 = 4000
and:
A - 4000 = 3000
A = 3000 + 4000 = 7000.
But remember that our original numbers are not exactly whole numbers, they are rounded up, so we could write them as:
A = 6999.8 (that would be rounded up to 7000)
B = 3999.7 (that would be rounded up to 4000)
The sum is:
A + B = 10999.5 (notice that this would be rounded up to 11000)
A - B = 3000.1 (this would be rounded down to 3000)
Answer:
x=1
Step-by-step explanation:
1) multiply the numbers
2) combine multiplied terms into a single fraction
3) distribute
4) combine fractions with common denominator
5) combine like terms
6) multiply all terms by the same value to eliminate fraction denominators
7) cancel multiplied terms that are in the denominator
8) multiply the numbers
9) add 35/4 to both sides of the equation
10) simplify
( add the numbers twice)
11) divide both sides of the equation by the same term
12) simplify
(divide the numbers, cancel terms that are in both the numerator and denominator, and last but not least move the variable to the left)
well and behold your answer is x=1
