Answer:
AB = 8
Step-by-step explanation:
AC = 36
AB/BC = 2/7
AB = (2/7)BC
AB + BC = 36
(2/7)BC + BC = 36
(9/7)BC = 36
BC = 36(7/9)
BC = 4*7
BC = 28
AB + BC = 36
AB = 36 - 28
AB = 8
======
Is AB/BC = 2/7?
8/28 = 2/7 YES
The area of the circle formed when the plane passes through the center of the given sphere is: 15π cm².
<h3>What is the Area of a Circle?</h3>
Area of a circle = πr² (radius of the circle = r).
Given the following:
- Radius of sphere = 8 cm
- Distance of the plane from the center of the sphere = 7 cm
Radius of the circle = √((radius of sphere)² - (distance of the plane from the center of sphere²)) = √(8² - 7²)
Radius of the circle = 3.87 cm
Area of the circle = π(3.87²) ≈ 15π cm².

Answer:
156800 Ways
Step-by-step explanation:
Since 3 states can be represented in 19600 ways, -->
now we have 2 ways different from the 1st of the 3 states -->
We can also select in 2 independent ways from the second of the 3 states -->
and 2 ways from the third of the 3 stats
This gives us 2 x 2 x 2 x 19600 or => 8 x 19600 giving us 156800 ways
Thus, we have our answer of 156800 ways
