Answer:
See explanations below
Step-by-step explanation:
Volume of the sphere is expressed as;
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 3³
V = 4/3 * 3.14 * 27
V = 4 * 3.14 * 9
V = 113.04cube units
For the secind sphere;
diameter = 12
radius = 12/2 = 6
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 6³
V = 4/3 * 3.14 * 216
V = 4 * 3.14 * 72
V = 904.32cube units

Answer:
16.5 =x
Step-by-step explanation:
Since this is a right triangle, we can us trig functions
tan theta = opp side / adjacent
tan 70 = x /6
Multiply each side by 6
6 tan 70 = x
16.48486452 =x
To the nearest tenth
16.5 =x
Answer:
5, -⅓
Step-by-step explanation:
x = 2:
4x + 3y = 23
3y = 23 - 4(2)
3y = 15
y = 5
x = 6:
4x + 3y = 23
3y = 23 - 4(6)
3y = -1
y = -⅓
