Surface area in units of PI = 2 x r x h +2 x r^2
first picture:
r = 7, h = 18
2 x 7 x 18 + 2 x 7^2
252 + 98
350 PI cm^2
2nd picture:
2 x 9 x 20 +2 x 9^2
360 + 162
522 PI in^2
If you look up "angles of 7 sided polygon" it would give a result of how many degrees polygons with 7 sides such as this one above would equal to. It's important to know that when finding x angles within.
7-sided polygons = 900 degrees in total
Since all the other angles except x are given, we can add all those up and set it equal to 900. So it would look like this:
Simply solve for x now.
So x = 111 degrees.
Hope this helps!
Answer:
51 vreels
Step-by-step explanation:
Step 1: Given data
Ratio of gespils to vreels on the planet Joop: 6:14
Step 2: Calculate the number of gespils per 120 vreels
Elentine has 120 vreels on her rew farm. If there are 6 gespils every 14 vreels, the number of gespils is:
120 vreels × (6 gespils/14 vreels) ≈ 51 vreels
Answer:
613 inches
Step-by-step explanation:
Area right triangle = 10,710
Formula for area of a triangle = 1/2(base x height)
We need to find the base because height and area is given
Reverse divide by 2 by doing multiply by 2
10,710 x 2 = 21420
Revers multiply by 612 by dividing by 612
21420 / 612 = 35
Base = 35
Formula for hypotenuse = a² + b² = c²
In this case a = 35, b = 612, and c = hypotenuse
35² + 612² = c²
1225 + 374544 = c²
375769 = c²
Square root of 375769 = 613
Hypotenuse = 613
