$use\pi = 3.14$
​

Answer 1

Step-by-step explanation:

The answer is in the above attachment

Answer 2

volume of the heap =  401.92 m ³

canvas cloth is required to cover the heap =  251.2 cm ²

Step-by-step explanation:

diameter of the cone = 16 m

radius of the cone = 8 m

height of the cone = 6 m

slant  height of the cone =

$l^2 = r^2 +h^2\\l = \sqrt{r^2+h^2}\\ l = \sqrt{8^2 + 6^2} \\l = \sqrt{100}\\ l = 10$

volume of heap = $\frac{1}{3}\pi r^2h$

= $\frac{1}{3}\times 3.14 \times 8\times 8\times 6$

volume = 401.92 m ³

canvas cloth is required to cover the heap = curved surface area of the cone = $\pi rl$

= 3.14 × 8×10

= 251.2 cm ²

hence ,

volume of the heap =  401.92 m ³

canvas cloth is required to cover the heap =  251.2 cm ²
