For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:

Determine the radius, to the nearest inch, of a large can of tuna fish that has a volume of 66 cubic

Mnenie [13.5K]

The radius of can is 2.524 inches

Solution:

Given that large can of tuna fish that has a volume of 66 cubic inches and a height of 3.3 inches

To find: Radius

Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,

The volume of cylinder is given as:

$\text{ volume of cylinder}= \pi r^{2} h$$

Where,

"r" is the radius of cylinder

"h" is the height of cylinder

$\pi$ is a constant equal to 3.14

Substituting the given values in above formula,

$66 = 3.14 \times r^2 \times 3.3\\\\66 = r^2 \times 10.362\\\\r^2 = \frac{66}{10.362}\\\\r^2 = 6.369\\\\r = 2.524$

Thus the radius of can is 2.524 inches
