determine the diameter to the nearest inch of a large can of tuna that has a volume 6068 inches and a height of 3.3 inches
anyanavicka [17]

Answer:

The diameter of can is<u> 48 inches</u>.

Step-by-step explanation:

Given:

Volume of can = 6068 inches.

And height(h) = 3.3 inches.

Now, to find the diameter.

Diameter = 2 × radius

Let radius be r.

So, by putting the formula of volume we get the radius:

Volume =\pi r^2h

6068=3.14\times r^2\times 3.3 (taking the value of π=3.14)

6068=10.362\times r^2

<em>Dividing both sides by 10.362 we get:</em>

585.60=r^2

<em>Using square root on both sides we get</em>:

24.199=r

<em>Radius = 24.199 inches.</em>

Then, we get the diameter:

Diameter = 2 × radius

Diameter = 2 × 24.199 = 48.398 inches.

Diameter = 48 inches (rounding to nearest, inch as in the place of tenth it is 3 which is less than 5.)

Therefore, the diameter of can is 48 inches.

Call center A and B offers equal wages.

<h3>what is Equation?</h3>

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The formula for wages = P/t

First, P= 15 dollars

           = 1500 cents

time= 1 hour= 60 minutes

then, the unit rate is

=1500/60

= 25 cents/ min

Second, P= 25 cents

       

time= 1 minutes

then, the unit rate is

=25/1

= 25 cents/ min

Hence, Call center A and B offers equal wages.
