What is the area of a circle with a diameter of 10?
The formula for the area of a circle is 2 * pi * r, where r is the radius. The diameter is 2 * radius, thus the radius is 10/2 = 5. Therefore, the area of this circle is 2*5*pi = 10pi.
What is the derivative of x^3+2x+1?
The derivative of x^3+x+1 is 3x^2+2, by taking the derivative of each item in the sum. The derivatiev of x^3 is 3 times x^2, by following the rule d/dx x^n = nx^(n-1) and the derivative of 2x is 2 * x^0 = 2. The derivative of d/dx(1) = 0.
