Answer:
n16
Step-by-step explanation:
Perimeter = 2(length + breadth)
370 = 2 ( 98 + b)
370/2 = 98 + b
185. = 98 +b
b = 185 - 98
b. = 87
Therefore breadth = 87 sq m
What I’m so confused but i hope you get the awnser from someone eklse not me

How-To:
Using the formula for area on the bottom of the can, (pi*r^2) you can then multiply by the amount of height missing, which is 4.
Since it was originally 10, you subtract 4 in order to get 6.
That's how to get 4.
Now, plug in pi*r^2 into a calculator (or if you must work it out, radius, r, is 10, so 10*10 is 100. 100*3.14159265 is 314.159265
Now multiply 314 by the height missing (4) to get approximately 1257.
Now for number 2.
It says it is dilated by a scale factor of 1:3 (from 1350). That means that it was made smaller, (that's what dilated means) by 3 for every 1. So take 1350 and divide it by 3 to get 450
