Class+Three

This week, the class will further investigate circles and will look at how to compute the area, using Pi and the radius. Your task is to become confident in calculating all the features of circles ;  - diameter  - circumference   - area   Remembering the value of Pi, you will use the application entitled '[|Geogebra]' to plan your solar system, taking note of the diameter and circumference of your circles, plus the circumference and area of each of the planet's orbits.

**__Remember the formula for circles; __** Diameter of a circle is given as D = 2R Circumference of a circle is given as C = 2πR Area of a circle is given as A = πR 2
