Answer:
180 sq. in.
Step-by-step explanation:
The formula for the volume of a circular cone is V = (πr^2h)/3
So, 900 = (15πr^2)/3
2700 = 15πr^2
180 = πr^2 = area of the circular base
Answer:
Area of the figure= 
Step-by-step explanation:
Area of the figure=Area of the middle rectangle+ Area the the two triangles
Area of the rectangle=Length*Width


Area of the triangle with the height of 2 feet and base= 3 feet
Area= 
=
Area of the triangle with the Height=3 feet and Base= 3 feet
Area= 

Total Area of the figure
