Help pls!!! The radius of a circle is 15 inches. Enter the area of the circle, in square inches. Round your answer to the neares
Bas_tet [7]

Answer:

706.5 inches squared

Step-by-step explanation:

The formula for the area of a circle is pi r^2. r being the radius. Because you have the radius, and pi is 3.14 in this case, your new formula is A=3.14(15)^2. 15 squared is 225, times 3.14 gives you 706.5

Your final answer is already in tenths so you don't need to round! Hope this helps :)) and brainliest is always appreciated

Can you guys teach me how to do this??
Vadim26 [7]

The usual margin of error we strive for is a 95% probability that our estimate is within the margin.   Assuming a normal distribution (and that we have a big enough sample not to worry about t tests) that corresponds to between minus and plus two standard deviations of the mean (remember the 68-95-99.7 rule).   So our margin of error is plus or minus two standard deviations.

Answer: ±2%

Talia gave her hairdresser a 20 percent tip, which amounted to $7. What was the price of the service before the tip?
mina [271]
I don't know if I did it right but here's my guess. I think you multiply 7 by 20% and that gives you 1.40 as a result. Compared to the other method I used (division), I'm pretty sure I'm right since the other result was 35. Doesn't make sense if the end amount was $7.
