A heap of wheat is in the form of a cone whose diameter is 10.5 m and height is 3 m. Find its volume. The heap is to be covered by canvas to protect it from rain. Find the area of the canvas required.



Sagot :

cone volume: V = (1/3) * π * r^2 * h, volume ≈ 28.97 cubic meters for canvas area use pythagorean theorem to find slant height (l) ≈ 6.05 m. Lateral surface area ≈ 98.5 square meters
