Well the answer for that question would be a greater number
Answer:
4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
I hope this helps!
The formula for the area of a circle is r² x π.
-Since we know the diameter of the circle, we can divide by 2 to find the radius of the circle.
10/2 = 5
-From here, we can substitute our values in. Since we're using 3.14 for pi, we'll substitute that as well.
(5)² x (3.14)
-And finally, we can solve to find the area of the circle.
(25) x (3.14)
(78.5)
Therefore, the answer is 78.5 meters.

The distance from Mercury to Sun is 57,9 * 10⁶km.
The distance from Venus to Sun is 108,2 *10⁶km.
The distance from Earth to Sun is 149,6 *10⁶km.
57,9 *10⁶+ 108,2 *10⁶+ 149,6 *10⁶ ≈ 315,7 *10⁶km
The distance from Neptune to Sun is 4503 *10⁶km.
That means their combined distanceis less than

The number of times scientific books were sold compared to mystery books is 1000 times or one thousand times.
<h3>How many copies of each book were sold?</h3>
The numbers provided to represent the number of copies that were sold from each book are given in scientific notation. In this type of notation, the exponent represents the number of zeros. Based on this principle, the number of books sold from each type is:
- Science fiction book: 10^6 = 1.000,000 (one million copies)
- Mystery book: 10^3 = 1.000 (one thousand copies)
<h3>How many science fiction book copies were sold in comparison to mystery book copies?</h3>
To find out this, simply divide the number of science fiction book copies into the number of mystery book copies:
- 1,000,000 / 1,000 = 1,000 (one thousand)
