Answer:
A =12.56 units^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
We know the radius is 2
A = pi (2)^2
A = 4pi
Using 3.14 as pi
A = 4(3.14)
A =12.56 units^2

Answer:
how much does he earn an hour?????
Step-by-step explanation:
Hello!
y = 2x³ + ax² - x + 3
Find the derivative using the power rule:
y' = 6x² + 2ax - 1
Substitute in the given slope and x value to solve for a:
3 = 6(1)² + 2(1)a - 1
3 = 6 + 2a - 1
4 = 6 + 2a
-2 = 2a
a = -1
