The area of the circle is 28.26 in²
<u>Explanation:</u>
Given:
Radius of the circle, r = 3 in
Area of circle, A = ?
We know:
Area of circle = πr²
The value of π is 3.14
Thus,
A = 3.14 X (3)²
A = 3.14 X 9
A = 28.26 in²
Therefore, the area of the circle is 28.26 in²

By solving a system of equations, we will see that the width is 170ft and the length 275 ft.

How to get the dimensions of the base?</h3>
For a rectangle of length x and width y, the perimeter is:
P = 2*(x + y).
Here we know that:
x = 2y - 65ft
p = 890ft = 2(x + y)
So we have a system of equations.
To solve this, we need to replace the first equation into the second one:
890ft = 2(x + y)
890ft = 2(( 2y - 65ft) + y)
Now we can solve this for y.
890ft = 4y - 130ft + 2y
890ft + 130ft = 6y
1020ft/6 = y = 170ft
So the width is 170ft, and we know that:
x = 2y - 65ft = 2*(170ft) - 65ft = 275ft
So the length is 275 ft.

Answer:
It is 27.4
Step-by-step explanation:
First you need to find the area of the three rectangle.
Area=base*high
You do 4*2 for about 3 times
Which is 8 for 4*2
Then you multiply it 3 more time and get 24.
After that you add 24+1.7+1.7 and get 27.4
