Answer:
28 ft²
Step-by-step explanation:
The area of a circle is 
, where r = radius. To find the radius, we split the diameter in half.
- 6/2 = 3
- Thus, the radius is 3.
Now, let's find the area of the circle and approximate pi to 3.14.
Therefore, the answer is 28 ft².
Answer:
The scale factor is 1/2
Step-by-step explanation:
Given
and 
Required
The scale factor from to
Take a corresponding side in both triangles.
We have:
The scale factor from to is:
P = 2(l + w)
p = 356
l = 96
356 = 2(96 + w)
356 = 192 + 2w
356 - 192 = 2w
164 = 2w
164/2 = w
82 = w
check....
p = 2(l + w)
356 = 2(96 + 82)
356 = 2(178)
356 = 356 (correct)
so the width (w) = 82 cm
We can see that there are 5 CDs, each of radius 9 cm
<u>Area occupied by 1 disc:</u>
Area of a circle = πr²
Area of disc = π(9)²
Area of disc = 3.14 * 81 = 254 cm²
<u>Area occupied by 5 discs:</u>
Area occupied by 5 discs = Area occupied by 1 disc * 5
Area occupied by 5 discs = 254 * 5
Area occupied by 5 discs = 1270 cm²
Answer:
$76.70 is the answer.
Step-by-step explanation:
18% of 65.00 is 11.70. I added 11.70 to $65.00, and got 76.70.
