natulia [17]

Answer:

350m

Step-by-step explanation:

capacity= volume/1000
but we know that volume of cylinder is πr²h so substitute it I'm the volume space
then substitute for π as 22/7, h as 1.4 , and also capacity as 539
539= ((22/7)×r²×1.4)/1000
when you simplify you get r as 350m

A coffee shop spends $408 for an order of 17 cases of paper cups.

solong [7]

Answer:

Option C is correct

$528 will the total cost spends by coffee shop

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates.

As per the statement:

A coffee shop spends $408 for an order of 17 cases of paper cups.

Unit rate per cases = $\frac{408}{17} =\$24$

Now, if If the coffee shop adds 5 more cases of paper cups to the order

then,

total number of cases = 17 +5 = 22 cases

To find how much total cost coffee shop spends.

Total cost = unit rate $\times$ total number of cases

= $24 \times 22 = \$528$

Therefore, total costs coffee shop spends = $528
