Answer:
Step-by-step explanation:
The equation for the area of a circle is A=.
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
Answer:
-439
Step-by-step explanation:
Think of the question as s(f(-7))
First replace x with -7 in the equation f(x)= 3x
s(-7) = 3*(-7)
s(-7) = -21
now it is s(-21)
we substitute -21 into the s(x) equation to get
That gives you 2-441 = -439
