The volume, V, of a cylinder is V= \pi^2h, where r is the radius of the cylinder and h is the height. Using rounding to the near

mylen [45]

To solve this problem you must apply the proccedure shown below:

You have that the radius of the cylinder is 2.75 inches and the height is 5.21 inches. Therefore, you only need to substitute these values into the formula for calculate the volume of a cylinder:

$V=\pi r^{2}h\\V=\pi(2.75in)^{2}(5.21in)\\V=123.78in^{3}=124in^{3}$

Therefore, as you can see, the answer is: The volume of the cylinder is 124 in³.

Which expression is equivalent to -2 1/4÷ (-2/3)

Talja [164]

Answer:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)=\dfrac{27}{8}=3\dfrac{3}{8}}$

Step-by-step explanation:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)\qquad\text{the quotient of two negative numbers is positive}\\\\=2\dfrac{1}{4}\div\dfrac{2}{3}\qquad\text{convert the mixed number to the improper fraction}\\\\=\dfrac{2\cdot4+1}{4}\div\dfrac{2}{3}=\dfrac{9}{4}\div\dfrac{2}{3}\\\\\text{dividing by a fraction is the same as multiplying by its reciprocal.}\\\\=\dfrac{9}{4}\cdot\dfrac{3}{2}=\dfrac{9\cdot3}{4\cdot2}=\dfrac{27}{8}\qquad\text{convert to the mixed number}\\\\=3\dfrac{3}{8}$
