Answer:
We need to take the diameter and divide by 2 to find the radius
Step-by-step explanation:
The volume of a sphere is found by
V = 4/3 pi r^3
So we need the radius
We know the diameter
r = d/2
We need to take the diameter and divide by 2
U subtract 4x by 5x and then you add 3 by -21 and the answer is x=18
Answer:
1,038 in2
Step-by-step explanation:
In a regular hexagon, the radius and side length are equal in length... That makes the answer 1038 in.2 correct?
15x²+16x+4 =0 (ax² +bx +c=0)
Δ = b²-4ac =256 - 4×15×4 =16
x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
