Question

hemisphere of radius 14 cm is completely filled with sand the same sand is poured on the ground so as to form a cone shaped heep of 7cm and then find the area of the base of the cone​

Answer 1

according to the question,

volume of hemisphere = volume of cone

${2/3 πr^3 = 1/3 πr^h}$

${2 × 14 × 14 × 14 = r^2 × 7}$

${r^2 = 2 ×2 × 14 ×14}$

r = √2×2 × 14×14

r = 2×14

$\boxed{r\:= \:28\: cm}$

Answer 2

Step-by-step explanation:

Area of base = π r^2= 22/7 × 14×14= 616cm^2
