1.	A heap of rice is in the form of a cone of basediameter 24 m and height 3.5 m. Find the volumeof the rice. How much canvas cloth is required tojust cover the heap?Solution:h 10 cmr 3.5 cm
Answer» Base diameter of cone = 24m Radius = 12mHeight of cone = 3.5mVolume of rice in conical heap = 1/3πr2h = 1/3 × 22/7×12×12×3.5 = 528m3now, slant height = √h2 + r2
