Does anyone know the answer to this?
1 answer:
Hey there!
First, let's find s:
s = (5 + 6 + 7) /2 = 9
Second, let's plug in the numbers into the formula:
A =
Third, let's simplify the numbers to get one number under the square root:
A = [tex]\sqrt{216}
Fourth, we'll find the square root of 216 to get the area:
A = 14.697
Therefore, your answer is A.
Hope this helps!! :)

Step-by-step explanation:
Standard form of a parabola with a vertical axis of symmetry:
If p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards.
From inspection of the graph:
- Vertex = (3, -1)
- Directrix = y = -3
Therefore:
- h = 3
- k = -1
- k - p = -3
Use the Directrix equation to find p
⇒ y = (k - p)
⇒ -3 = -1 - p
⇒ p = 2
Therefore the equation of the conic section is:
Rearranging in standard form :
Answer:
Volume = (250π√3)/3 unit³
Step-by-step explanation:
The shape is a solid sphere
Where rho = ρ
ρ ≤ 5
Where Phi = φ
φ = π/6 (lower limit)
φ = 5π/6 (upper limit)
Note 1π rad = 180°
We would apply triple integrals and spherical coordinates to solve for the volume of a solid sphere.
See attachment for details
From calculations,
The volume of the portion of solid sphere = Volume = (250π√3)/3 unit³
