The circumference of wheel is 6.28 feet.

Step-by-step explanation:

Given,

Area of prize wheel = 3.14 square feet

Area = πr²

3.14 = 3.14(r)^2

Dividing both sides by 3.14

\frac{3.14}{3.14} = \frac{3.14(r)^2}{3.14}\\1=r^2\\r^2=1\\r=1

Circumference = 2πr

Circumference of prize wheel = 2*3.14*1\\

Circumference of prize wheel = 6.28 feet

The circumference of wheel is 6.28 feet.

Keywords: area, circumference

A cafe sells puffs. 5/9 are beef and 1/3 are chicken. The remaining 18 are tuna. Calculate 1. What fraction of the puffs are tun
Ksivusya [100]
Let n be the total number of puffs. Now we can write:
n=\frac{5}{9}n+\frac{1}{3}n+18
Adding the fractional value of n, we get:
n=\frac{5+3}{9}n+18
Simplifying and rearranging gives us:
n-\frac{8}{9}n=18
Therefore we can simplify to get:
\frac{1}{9}n=18
and finally
n=18\times9=?
The fraction of the puff that are tuna is found from:
\frac{18}{18\times9}=\frac{1}{9}

You have a set of nested boxes whose lengths vary directly with their widths. One box is 2.5 in, wide and 5.5 in. long. A second
Anna11 [10]

Answer:

B

Step-by-step explanation:

If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.

2.5     =      3

5.5             x

cross multiply

16.5=2.5x

and divide

16.5/2.5 and you get your answer
