Answer:
The answer is in the attached file below
Step-by-step explanation:

The given figure is a sphere :

_____________________________

3 sin x = 2 ( 1 - sin² x )
3 sin x = 2 - 2 sin² x
2 sin² x + 3 sin x - 2 = 0
Substitution: t = sin x
2 t² + 3 t - 2 = 0
t 1/2 =

t 1 = 1/2
t 2 = - 2 ( this solution is not acceptable )
sin x = 1/2
Answer:
x 1 = π / 6 + 2 kπ, x 2 = 5 π / 6 + 2 k π, k ∈ Z
Answer:
Flooring: 155 | Cost: 968.75
Step-by-step explanation:
10 x 15 1/2 = 155
then multiply the 155 with the 6.25
you will get 968.75
so the cost is $968.75
The area is Base * Height
Area = b * h
b =12 3/4 in
h = 2 1/2 in
Area = 12.75 * 2.5 = 31.875 or 31 7/8 square inches.
