A solid cube of side 7 cm is melted to make a cone of height 5 cm, find the radius of the base of the cone. About the author Rose
Step-by-step explanation: Side of cube=7cm Height of cone=9cm Let the radius of base of cone be\quad ‘b’ cm Now, volume of cube=volume of cone (7)^3=3/1×22/7×r^2×5 r^2=(343×3×7)/110=65.48 r= √(65.48) =8.09cm Reply
Step-by-step explanation:
Side of cube=7cm
Height of cone=9cm
Let the radius of base of cone be\quad ‘b’ cm
Now, volume of cube=volume of cone
(7)^3=3/1×22/7×r^2×5
r^2=(343×3×7)/110=65.48
r= √(65.48) =8.09cm
Step-by-step explanation:
above is the answer of given question
