Answer:
2.25π in²
Step-by-step explanation:
The area can be found from the circumference using the formula ...
A = C²/(4π)
Putting in the given dimension, you have ...
A = (3π)²/(4π) = (9/4)π = 2.25 π . . . . in²
2n+9+5n=30 combine like terms on left side
7n+9=30 subtract 9 from both sides
7n=21 divide both sides by 7
n=3
Answer:
B | 6
Step-by-step explanation:
First, find the length of the wire by finding the perimeter of the rectangle
2(5) 2(7) = 24
If a square has 4 sides, put 24 as the numerator and 4 as the denominator.
24/4
Now, divide it and you'll get 6, the answer.
It all the way across a circle so
7.3+7.3=14.6 so that your answer
