Finding the Measures of Angles in Right Triangles
Just remember the right righteous Chief SOH-CAH-TOA (pronounced SO-KAH-TOE-AHH) who lives in a right-triangle tepee. (Sorry about failing political correctness.)
SOH-CAH-TOA stands for
Area and Circumference of a Circle
Tweedle-dee-dum and Tweedle-dee-dee,
Around the circle is pi times 3,
But if the area is declared,
Think of the formula pi "r" squared.
"Around the circle" means circumference.
Circumference = pi x 3
Area = pi x r squared < BR>
