First, we find the diameter.
12.56 divided by 3.14 = 4.
Next, find the radius.
4 divided by 2 = 2.
Then, use the formula to calculate the area.
2 times 2 times 3.14 = 12.56 is your area.
In this case, the area and the circumference are the same. Sometimes that is not that case though. Hope it helps! :)
Answer:
Wide and length are: 3x + 10 and 3x - 10
Step-by-step explanation:
9x²-100 = (3x + 10) (3x - 10)
Fx-2cos(x)=0

Answer:
n = -4
Step-by-step explanation:
Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4
