15
Step-by-step explanation:
Using the PEMDAS method will allow you to solve the expression. First, (-10)-(-11)= 1. Then you would subtract the -10 which would give you -9 as your full answer!
From the division property, the required kansui is 5/32 tablespoon.
What is division?
One of the four fundamental arithmetic operations, or the process by which two or more numbers are added together to create a new number, is division. Multiplication, addition, and subtraction round out the list of operations.
Given that a batch of mooncake contains 1/4 tablespoon of kansui.

Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108
now h = r/2 so we have:-
2pi r^2 + pi r^2= 108
3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
