How to Piece Together Areas: Compound Figures with Triangles, Semicircles, and Quarter Circles
Today, we’re stepping into the exciting world of compound figures. These are shapes made up of more than one basic geometric figure, like triangles, circles, or semicircles. This approach will help us break down more complex shapes into manageable pieces and find their area. For additional educational resources,.
How to Calculate the Area, Perimeter, and Radius of Quarter Circles
TL;DR: Picture a pizza cut into four equal slices — grab one and you’ve got a quarter circle. It’s bounded by a 90-degree arc and two straight radii meeting at the center. Area is just the full circle’s area divided by 4. Perimeter combines the curved arc (which is one-fourth of the full circumference) with […]
