—radius is 1/2 the diameter so if the diameter is 6, the radius would be 3.
—the circumference is 2pier
so you would use your calculator and use the pie symbol or 3.14 and multiply 2*3.14*3 (3=radius for my example)
— the area is pie r^2
so you would multiply 3.14*3 squared

what is the similarity ratio of the smaller to the larger similar cylinders? enter your answer as a:b​
Andre45 [30]

Answer:

2 : 3

Step-by-step explanation:

Given:

The two cylinders are similar. So, their corresponding dimensions must be in proportion.

\frac{\textrm{Radius of small cylinder}}{\textrm{Radius of larger cyclinder}}=\frac{12}{18}=\frac{2}{3}=2:3

\frac{\textrm{Height of small cylinder}}{\textrm{Height of larger cylinder}}=\frac{20}{30}=\frac{2}{3}=2:3

Therefore, the similarity ratio of the smaller to the larger similar cylinders is 2 : 3.

adelina 88 [10]

The inequality for the maximum number of bottles of juice she can buy

6.13+ 2.08b <20.00

Option B

Given

Melissa has $20 to buy bagels and juice for her class

Box of bagels :   6.13 including tax

Bottle of juice: 2.08 including tax

She will buy only one box of bagels that is for 6.13

Let 'b' be the number of bottles of juice she can buy

Total cost should be less than 20 dollars

6.13(one bagels) +2.08(bottles of juices)<20

So the inequality becomes

6.13+2.08b
