Answer:
416 mi
Step-by-step explanation:
In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.
<em>Remember to find the area it is length x width</em>
- 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
- Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
- In total, you will add 72+72+72+72+64+64 which equals 416
Answer:
B :it is the ratio of the area of the circle to the area of the square from a cross section.
Step-by-step explanation:
had this question on ed2020 and got it right^
"Formula of a circle" is too vague to be meaningful. Perhaps you meant, "Formula for the area of a circle in terms of its circumference."
The area of a circle in terms of its radius is A = πr^2. To put this formula to use, we have to know the radius of the circle. The circumference of a circle in terms of its radius is C = 2πr, so a formula for the radius is r = C / (2π).
Now let's find a formula for the area of a circle in terms of its circumference:
C C^2
A = πr^2 = π { ---------------- }^2 = ------------
2π 4π
or:
A = (C^2) / 4π
