Answer:
x = 13
Step-by-step explanation:
Take the square root of both sides
The formula for a cylinder's volume is
V = π r² h
V = 1345.6
π = 3.14
r = 5.8 cm
1345.6 = 3.14 * 5.8^2 h Multiply 3.14 and 5.8^2 together.
1345.6 = 105.6 h Divide by 105.6
1345.6 / 105.6 = h
h = 12.73 cm <<<< answer.
I don't see anything wrong with what I've done but I don't see the answer anywhere. Estimating 1345 can be rounded to 1300.
pi * 5.8^2 = 3 * 35 = 105 which we could round to 100.
1300 / 100 about = 13 So the answer should be in the region of 100.
I cannot see any reason to believe there is an error. If there is something that has not been copied correctly, I'd like to know what it is.
The answer is, (1, -5)...
It is okay to take the inverse of both side given that you remember to exclude the value that make the denominator zero which is in this case r=-1
