The volume of a cylinder is 539 cm cube and the circumference of the base is 22 cm. find the height of the cylinder.

Alexandra [31]

Answer:

13.994 $cm (5.sf)$

Step-by-step explanation:

We know that the base of the cylinder is a circular base.

So circumference of base = $2\pi r$

Given $2\pi r=22cm\\\\r=\frac{22}{2\pi } \\r=\frac{11}{\pi } cm\\$

Volume of a cylinder = $\pi r^{2} h$ = 539 $cm^{3}$

Substitute r into the formula for volume of cylinder.

$\pi (\frac{11}{\pi } )^{2} h=539\\\pi (\frac{121}{\pi ^{2} } )h=539$

Now, we will cancel $\pi$ from the numerator and denominator.

$(\frac{121}{\pi } )h=539\\h = \frac{539}{\frac{121}{\pi } } \\h = 539 * \frac{\pi }{121} \\h = 13.994cm(5s.f)$

4a-9b=22

substitute b=-2

4a -9(-2) = 22

4a +18 =22

subtract 18 from each side

4a = 4

divide by 4

a =1
