7th grade homework for Friday September 28th, 2012

Remember when using formulas you need to read carefully what you are being asked.
For exercises 11 and 12, you need to find the area of each figure. Remember that the are of a rectangle is length times width, and the area of a square is side-squared.

Ex. 11, 12 p. 83 and Ex. 27p.84

Find the area of each figure:
11) Recangle: Length = 5in; Width = 2.5 in
12) Square: Side = 0.5cm

27)The circumference C of a circle can be found using the formula C=2Πr, where r represents the radius of the circle. What should Olivia do to write a formula to find the radius of a circle?

Remember that homework is meant to be done on a separate piece of paper.
Also, tomorrow we have an open book quiz. Just because it's open book don't forget to study, you DO need to study.
