Area= length × width. 2.2×2.2=4.84
Answer:
This is FALSE. Two supplementary angles add up to 180 degrees.

A cone is a <em>3-dimensiona</em>l shape that consists of a <u>circular</u> or <u>flat</u> surface and a <u>curved</u> side. Thus the <em>volume</em> of the given cone is 4.1 ![mi.^{3}](https://tex.z-dn.net/?f=mi.%5E%7B3%7D)
A cone is a<em> 3-dimensiona</em>l shape that consists of a <u>circular</u> or <u>flat</u> surface and <u>curved</u> side. Its <em>volume</em> can be determined by;
The <u>volume</u> of a <u>cone </u>=
![\pi](https://tex.z-dn.net/?f=%5Cpi)
h
where r is the <u>radius</u> of its <u>flat</u> surface, and h is its <em>height</em>.
From the given question, we have to <u>determine</u> the value of h using the <u>Pythagoras</u> theorem.
Such that;
=
+ ![/Adj 2/^{2}](https://tex.z-dn.net/?f=%2FAdj%202%2F%5E%7B2%7D)
=
+ ![1^{2}](https://tex.z-dn.net/?f=1%5E%7B2%7D)
16 =
+ 1
= 15
h = ![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
Thus the<em> volume </em>of the<em> cone</em> =
![\pi](https://tex.z-dn.net/?f=%5Cpi)
h
=
x
x
x ![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
= 4.0574
Therefore the <u>volume</u> of the given<em> cone</em> is 4.1 ![mi.^{3}](https://tex.z-dn.net/?f=mi.%5E%7B3%7D)

Answer:
$5,552.26
Step-by-step explanation:
First, set up an equation using exponential decay
Let y represent the cost and let x represent the number of years
y = 15,000(0.78)^x
Plug in 4 as x, and simplify:
y = 15,000(0.78)^4
y = 5,552.26
So, in 4 years, the car will be $5,552.26
Answer:
x = 6
