Circular Prism Area




Area of base x height

We need to find the area of the base first
Our formula d/2=r 0.26m/2= 0.13m
0.13x0.13xπ=0.053m
0.053m=Area of base


0.053mx2.4m= 0.1272mx35m=4.452m
rounded= 5m














Cylinders


Diameter- cuts through the circle
Radius- Half the diameter
Circumference- Perimeter of the square

Formulas

To Find:
Circumference= pi x d
Radius= d/2
Diameter=r x 2, c/pi Area=r x r x pi
