Question

A heap of wheat is in the form of a cone whose diameter is 12m and height is 4.5m Find it's volume. The heap is covered by canvas to protect it from rain. Find the area of the canvas required​

Answer 1

volume is 169.56 cubic m

total area of canvas is 141.3 sq. m...

hope it helps

Answer 2

$\huge \boxed{hello \: there}$

Radius of the conical heap=6 m

Height=4.5 m

Volume of the conical heap=1/3πr²h

➡1/3×3.14×6×6×4.5

➡169.56 m³

Area of the canvas required=Curved surface area of the cone

➡CSA of a cone=πrl

First, we need to calculate the slant height,

l²=r²+h²

l²=(6)²+(4.5)²

l²=56.25

l=7.5 m

Therefore, area of canvas required:

➡3.14×6×7.5

➡141.3 m²
