20π or 62.8 roughly
Step-by-step explanation:
Hello!
The formula for finding the circumference of a circle is 2rπ:
In that case, all we have to do is substitute 10m for our r.
2 × 10 = 20.
So circumference will be 20π.
Using 3.14 for π:
We get that 62.8 is a rough estimate for the circumference.
Really, it's 62.831..... going on forever since π is irrational.
Thus, the answer exactly is .
Hope this helps!

The equation representing the given relationship is
y = 0.50x + 15
Given, The cost for renting a car a day is $0.50 per mile, plus a $15 flat fee.
we have to find an equation to represent the given relationship.
Let the number of miles driven be, x
and the total cost be, y
total cost = cost per mile × miles driven + flat fee
Total cost = 0.50 × miles driven + 15
y = 0.50x + 15
Hence, the equation representing the given relationship is
y = 0.50x + 15
