The Formulas
Similar to the rectangular prisms, Triangular and cylinders use the same formula.
The difference is that you need to know how to calculate the area of:
Triangle's Area = Base x Height ÷ 2
Circle's Area = π × radius²
- Area of Triangle x Depth
- Area of Circle x Depth
The difference is that you need to know how to calculate the area of:
- A Triangle
- A Circle
Triangle's Area = Base x Height ÷ 2
Circle's Area = π × radius²
