Question

a piece of metal having the form of a quadrant of a circle is rolled up so as to form a conical vessel find its contents .when the radius of a quadrant is 10 cm

Answer 1

So as per the question
we have to find the volume of that cone .
We know that vol. of cone is 1/3(pie x r^2 x h)
so here , h = r
now so vol. = 1/3(pie x 1000) cm^3

Answer 2

a quadrant of sphere =1/8 of volume of sphere
1/8×4/3×22/7×100
11/21×100
1100/21cm³

volume of conical vessel =1100/21cm³
if its radius remains same then
1/3×22/7×10×10×h=1100/21
100h=50
h=1/2

hope it helped ,if really yes then please mark as brainliest

and if its wrong then really sorry dear
