What is the formula needed to find the area of this 2D figure?
A = ๐r2
A = ยฝ bh
A = bh
A = ยฝ (b1 + b2) h
2
What formula will help you find the surface area of this 3D figure?
SA = (ยฝ bh1) h2
SA = 2๐rh + 2๐r2
SA = ๐rl + ๐r2
SA = 4๐r2
3
What is the formula needed to find the area of this 2D figure?
A = bh
A = ยฝ (b1 + b2) h
A = ๐r2
A = ยฝ bh
4
What formula will help you find a missing side length of this figure?
1/2bh
a2 + b2 = c2
2๐r
sum of all sides
5
