Answer:
4pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
where r is the radius
The radius of a circle is found by
r =d/2 where d is the diameter
r = 4/2 = 2
So A = pi (2)^2
pi (4)
4pi

Answer:
I didn't get you
Step-by-step explanation:
what??
A polynomial with three terms is called a trinomial. Trinomials often but not always! have the form x2 + bx + c. At first glance, it may seem difficult to factor trinomials, but you can take advantage of some interesting mathematical patterns to factor even the most difficult-looking trinomials.
It’s a lot but hopefully I help:)
