The formula for the area of a circle is A = (pi)r^2 So if you plugged in the numbers you would get this equation A = (3.14)97^2 Solve the equation and you would get your answer which is 29544.26 Hope this helps! :)
first, you combine the terms together to get -7x^-1. you cant have negative exponents in the numerator so you move the x^-1 to the denominator. once it move its becomes positive then.
With polynomials the degree is the highest power x or whatever the variable is raised to. In this case, the degree is 3 since the highest power x is raised to is x^3
