Answer:1 2 DNE
Step-by-step explanation:
Answer:

Step-by-step explanation:
The figure is made up of a rectangle and two semicircles.
We find the area of the rectangle using the formula;



We find the area of one of the semicircles and multiply by 2;
The area of the semicircles

We substitute
and
to obtain;



The area of the figure is


To the nearest tenth we have;

The correct answer is A
The ordered pairs are:
<span>{(1, 80), (2, 240), (3, 720), (4, 2160)}
with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160
The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3
The equation is:
a_n = 80 * 3^(n - 1)</span>
Answer:
It should just be the radius
Step-by-step explanation:
The radius is half the diameter of the circle and all you’re doing is taking the radius multiple times
