and B must be invertible, we have UA=B, since A is invertible. A^-1 exists, by multiplying with A^-1,
we have UA A^-1 =B A^-1. But AA^-1 = I (identity matrix)
and XI=X, for all matrix X, we find UI= B A^-1, and U= B A^-1.</span>
Answer:
h = s / π.r²
Step-by-step explanation:
the given equation is s = π.r².h
Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.
This only possible when we divide term on both the sides by π.r²
s/π.r² = π.r².h/π.r²
h = s / π.r²
Therefore h = s / π.r² is the right option.
6m + 6m + 15m + 15m = 42m
no 40m will not be enough
Can barely see the questions ! Retake a picture if you can.
Hello!
To find the area of a hexagon you do 3

where a is one of the sides
Since the perimeter is 60 we can do 60/ the sides of the shape
60/6 = 10
So one side is equal to 10
you put that into the formula to get the area of a hexagon and you get 259.81
Hope this helps!
