Answer:

1,Area = πr² Circumference = 2 πr So first we solve for r from area: 25 π = πr² 25 = r² r = 5 So we know that radius is 5 cm. Now substitute r to 5 in circumference formula: C = 2π(5) = 10π

Option A: d(t) = 360-60t is the right answer

Step-by-step explanation:

We will write the given problem in terms of function to find the correct answer.

Let d(t) be the function and t be the number of hours.

Total distance is 360 miles and with each passing hour the distance will reduce 60 miles

So,

The function is:

$d(t) = 360-60t$

Hence,
