How do you evaluate: To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Answer:
The formula of area is Pi×R×R
and then you add all sides and answer of your question is 30cm
No
645 becomes 650 when rounded to the nearest ten
645 becomes 600 when rounded to the nearest hundred
Your answer: A=50cm²<span><span>Base: 5cmHeight: 20cm</span></span>A=hbb2=20·52=50cm²
