First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle (

) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer
Answer: Today's temperature : 2t -10
Step-by-step explanation:
Hi, to write the expression of the statement given we have to analyze each phrase:

<em>The temperature today was 10 degrees colder than</em>: It means that we have to subtract 10 degrees :(-10)
Mathematically speaking:
Today's temperature : 2t -10
where t = yesterday's temperature
