7m = 49 solve the equation by trial and error method
1 answer:
Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.
Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,
So we check, but
which means m must be bigger.
So we pick m to be 8 and check, but
which means m must be smaller.
Since only natural number between 6 and 8 is 7 we pick m to be 7 and check, and
.
The answer is therefore 7.

Answer:
Step-by-step explanation:
Since the box contains a cylinder, the height of the box must be gt; = cylinder height
And the area at the bottom of the box is definitely larger than the area at the bottom of the cylinder.
The area at the bottom of the cylinder is PI r squared,
If the bottom of the box is a square, then the area of the bottom is 4r^2, whereas the bottom tends to be polygon, which is equivalent to cutting the circle into equal parts by circle cutting.
So the area at the bottom of the box is ，
It follows that the volume of the box is greater than the volume of the cylinder
