v=37.68 inches cubed
In this exercise is given that a can of tuna which is a cylinder has a diameter of 4 inches and a height of 3 inches, and it is asked to find its volume. In order to find the volume of the can of tuna, you should substitute the values for the radius and height into the previous mention formula. But first of all, the radius of the cylinder should be find it.
Now that the radius of the cylinder is known you can substitute the values into the formula, V=πr^2(h).
V=(3.14)(2 in)^2(3 in)
V=(3.14)(4 in)(3 in)
The volume of the can of tuna is 37.98 cubic inches.
you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
