Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The radius of the cylinder is
The height of the right cone is
From the diagram we see that container B is a semi -sphere and the volume of a semi-sphere is mathematically represented as
The question tells us that both container has the same radius so
This equivalent to
Solving the equation will produce the same formula as
Assuming you mean 90 students and not 90% its 27 got an A
I think it's c............
The answer:
<span>according to the question the length is its width, that means
w=l
</span><span>She wants to enlarge the picture to have an area of 192 in2,
that means Area = </span>wxl = 192 in²
so, since w=l, we can write that Area = wxl =w²=l²= 192 in², this implies:
w=sqrt (192) = 13.85 in
finally the width w = 13.85, and the length l= 13.85 because w=l
