A = π r^2
A = 9^2 <span>π
</span>A = 81<span>π
if using </span>π = 3.14 then
A = 3.14 x 81 = 254.47 ft^2
answer: 81π ft^2 or 254.47 ft^2
hope that helps
Answer:
Volume of cylinder = 
Step-by-step explanation:
Given : A cylinder fits inside a square prism.
To find : The volume of cylinder
Solution : Refer the attached graph.
Area of circle =
Area of square =
Side of square = diameter of circle= 
Diameter = 2r
∴ Area of square= 

Area of circle is
of area of square.
Volume is always = area × height
Volume of prism = Area of square × h = 
Volume of cylinder = Area of circle × h = 
Now, rate

⇒Volume of cylinder is
of Volume of prism.
Volume of Cylinder =
Volume of cylinder = 
Volume of cylinder =
