It is valid.
The three angles must add up to 180. So, if one is more than 90, the other two have to be less than 90.
The equation
can be used to find the radius.
Step-by-step explanation:
Given,
Volume of large can;
V=πr(r)h
V=πr²h
Dividing both sides by πh

Taking square root on both sides

Putting π=3.14

The equation
can be used to find the radius.
