Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.

Hi,
Based on this, I am not sure how close they want the number to be “8” but here is the work:
1.) 9
2.) 7
3.) 7
4.) 8
5.) 8
Most likely it is 4 and 5 but it could be others if they think it’s close to 8 thank you!
Answer:
to help, i will demonstrate the first problem. This is a right triangle. We know this because it is a 45-45-90 triangle.
Because of this we know that the sides are 2 and 2 (they must be equal).
Now we need the hypotenuse- the side across from the right angle (in other words, the diagonal line).
To do this we take 2 times the square root of two. This makes it 2.82.
