Objective and Summary:
SWBAT compute area of a circle

SYW in formative is optional for today (except for on the exit ticket)

Area 1—Calculate the area of the following circles (leave in terms of π)

A circle with a radius of 12 feet.

Calculate the area of the following circles (leave in terms of π)

A circle with a diameter of 4 feet.

Calculate the area of the following circles (leave in terms of π)

The circle in the provided diagram:

Pep--Ms. Jarvis wants to paint a large red circle onto the wall of her apartment as a decoration. She plans to paint the circle with a diameter of 22 inches.

What will the total area of the circle be once she fills it in? Use 3.14 to approximate π.

Symbols for copy and paste: π , r²
Note: You can type either r² or r^2 (they mean the same thing). ^ comes from shift+6 and means an exponent.

"The area of the circle is..."

Circle the Sequel--Ms. Portilla is doing some art at home and is practicing drawing circles. She is curious about how much material she will need to cover the circle in the image.
Help her find how many square centimeters of material she will need. Use 3.14 to approximate π.

You may use the calculator below for this question

"Ms Pfannenstein needs..."

SPICY--Try if you have time (optional)

Think outside the Box--Mr. Kovalik tells you that the area of a perfectly circular room is 153.86 square feet.
What must the radius of the room be?

(Need a hint? Work backwards)

Star Student--Student McStudentson says that the area of a circle with a diameter of 10 centimeters must be 78.5 cm^2.
Do you agree or disagree with him? Explain. If he made a mistake, point out the mistake and explain how he could fix it.

"I (agree / disagree) with McStudentson because..."

Symbols for copy and paste: π , r²

You MUST SYW on formative for credit

CFS:
#1: Writes appropriate formula
#2: Substitutes correct measurements and calculates accurately
#3: Includes accurate units

This is a shorter classwork, so please go to IXL's starred section and find more problems for finding Area of a circle. 
You can also find the skill by searching code YA8

Keep working on challenge skills after that!
