Question

A hemispherical lead shot of radius 7cm is cast into a right circular cone of height 49 cm. Find the radius of base

Answer 1

Answer:

Step-by-step explanation:

Volume of hemispherical lead shot=volume of cone

Radius of hemisphere=7cm

Volume of sphere=4/3πr³

4π/3*7*7*7

Now volumeof right circular cone=1/3πr²h

π/3*r²*49

So now we will compare the equations since volume is equal

4π/3*7*7*7=π/3*r²*49

4*7*7*7=r²*49

4*7=r²

28=r²

r=√28

Hope it is correct and helps u to find correct if wrong

Thank you
