Answer:
31.42 units²
Step-by-step explanation:
Formula for the area of a circle: π×r² (pi times the radius squared)
if the radius is 10 units, plug that into the equation by making it:
π×10²
first do 10²=100
then multiply 100 by π
this gives you about 31.42 units²

Answer:
x² - 5x - 36
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last) to solve. x times x is x², so that is the first term of our trinomial. The outside terms are x times 4, or 4x. The inside terms are -9 and x, so -9x. The last terms are -9 times 4, or -36. We can add the like terms of 4x and -9x to get -5x. So, your trinomial is x² - 5x - 36.
