Translate this verbal expression of the formula into an algebraic expression.

Step-by-Step Solution

Answer

The expression is $2\pi rh+2\pi r^2$.

Step 1- Observe the provided statement

According to the statement the variables are r and h. Also there is symbol $\pi$. There is an addition.

Step 2 – Use the observation and provided information

By using the provided information observation, form the expression.

 

$2\pi rh+2\pi r^2$

Step 3- Make the conclusion

As the obtained expression is completely matching with the provided information so the expression $2\pi rh+2\pi r^2$ is the required expression.
