The correct answer is Choice A: 1/6
If you look at the table, there are 6 spots where the 2 numbers are the same. They are in a diagonal row from the bottom left to the top right.
6 out of 36 makes the fraction 6/36 which is 1/6
Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then
Where
--- Perpendicular bisector
So, the equation becomes
Recall:
Answer: 2
Step-by-step explanation:
Move all terms to the left side and set equal to zero. then set each factor equal to zero .
x = - 6 - y
______
4 + r
Answer:
64 × pi m²
Step-by-step explanation:
the formulas needed for the surface area of a cone are :
base area plus the "mantle", the lateral "wall" around it.
the base area is a circle.
so, that formula is Ac = pi×r²
the "wall" formula is Aw = pi×r×s
r = radius
s = slant height = 12
the formula for the surface area of a sphere is
As = 4×pi×r²
we know now, that both surface areas are the same, and also the radius is the same for both objects.
Ac + Aw = As
pi×r² + 12×pi×r = 4×pi×r²
=>
12×pi×r = 3×pi×r²
12×pi = 3×pi×r
12 = 3×r
r = 4 m
now, we only need to use this value of r in our formulas for surface areas, like for the sphere :
4×pi×r² = 4×pi×4² = 4³×pi = 64×pi
