228.5 I believe. 14/49 is 3.5. 18+7 is 25x9 is 225. 225+3.5 would be 228.5
Circumference of a circle having radius of 27 yard can be found using the formula, π = 2(Area of Circle)/r, which is C = 169.6 yd
<h3>What is the Circumference of a Circle?</h3>
- Circumference of a circle is the distance round the circle.
- Circumference = Perimeter
- Circumference of a circle without using π = 2(Area of Circle)/r.
Given:
radius of circle = 27 yd
Thus:
Area = πr² = π(27)²
Area = 2,290.2 yd²
Circumference of a circle without using π = 2(2,290.2)/27
= 169.6 yd.

2+42/-2-5(-3) Multiply -5 and -3.
2+42/-2+15 Now, add the non fraction numbers. (2 and 15)
17+42/-2 Here, you want to reduce the fraction if you can, and yes, you can. Find the divisible number that is the lowest one that both can be evenly divided by. For this problem, it’s -2.
17-21. And from here, its easy. Just a simple subtraction problem.
-4 should be the correct answer.
Answer:
33 minutes
Step-by-step explanation:
We know that the initial amount of money on the card is $15 and that she had $12.03 after the call. We can subtract 12.03 from 15 to find out how much the call cost.
15 - 12.03 = 2.97
Now that we know the cost of the call is $2.97, we can divide it by the amount it cost per minute (9 cents) for Susan to make an international call:
First, convert $2.97 to cents:
$2 is the same as 200 cents.
200 + 97 = 297
Now, take 297 and divide it by 9:
297/9 = 33
The call lasted 33 minutes.
