,
Step-by-step explanation:
we know that
The area of a circle is equal to

Part 1) Find the area of the circle with diameter 6 m
we have
-----> the radius is half the diameter
substitute the values

Part 2) Find the area of the circle with diameter 10 m
we have
-----> the radius is half the diameter
substitute the values

Part 3) Find the area of the circle with diameter 13 m
we have
-----> the radius is half the diameter
substitute the values

Hey there!
I just worked it out and the answer is D. 4y^2-10y-1
I’ve just studied these long equations and then having to simplify the expressions in algebra. I really hope my answer benefits you in the best way!

Using (a-b)(a+b)= a2-b2
Simply the product
x2-62
Evaluate the power
x2-36
We have a geometric sequence----------- > <span>{-4, 12, -36, ...}
</span><span>
the formula is a(r)^(n-1)
a------------- >a is the first term------------ > -4
r--------------- > </span><span>is the common ratio------- > 12/(-4)=(-36/12)=-3
n--------------- > is the number of terms
</span>The fifth term is -4[(-3)^(5-1)]=-4[(81]=-324
the answer is -324
