### Jump Start: Sept 24, 2009

Find the area of the circle.

14 in

• 1. Find the perimeter of a rectangle that has a base of 9ft and a height of 40 ft.

• What is the area of the rectangle in question 1?

• Find the area of a circle with a diameter of 18cm.

All players will remain quiet and respectful during play or the game will end.

Only the elected speaker of each team will be allowed to answer for the team.

Each team will have 30 seconds to come up with an answer to each question unless Ms. Lagroon deems a question to require longer response time.

We will roll a dice to see who goes first and go in a rotation.

Only the team whose turn it is can answer the question and get credit .

If a team fails to answer correctly, we will roll for another team to get a chance.

If you answer correctly, you will receive the number of points the question was worth.

If you answer incorrectly, the number of points the question was worth will be subtracted from your total.

The winning team will receive 5 bonus points on their tests.

Everyone must participate. People that do not participate will receive a zero participation grade for today.
