Answer:
18.84 ft
Step-by-step explanation:
The formula for the circumference of a circle is C = πd or C = 2πr
We will use C = 2πr since we have r given in the photo
- We just need to substitute our values into the formula:
- C = 2(3.14)(3) = 18.84 ft
This is a percent problem which means
You take the amount that has been completed over the total amount. You then multiply it by 100%
30/120*100=25%
What size is the second pizza supposed to be?
Answer:
95% picked pizza
Step-by-step explanation:
We can get this answer by following a few different steps. Firstly, we need the total amount of students. We get this number by adding the amount of students who wanted pizza (19 students) and the amount of students who wanted burgers (1 student). When we add those we get the total number of students, which is 20. Now, we can set up a fraction to see what amount of students out of the total number of students wanted pizza.
This would be 19/20
Now, you plug this in your calculator and will get 0.95
To turn this, or any other decimal, into a percentage you multiply by 100%.
So, multiply 0.95 x 100% = 95%
Hope this helps :)
