Answer: 12cm
Step-by-step explanation:
Let the radius of the new sphere be r.
Volume of 3 spheres= volume of new sphere
4/3 π(6^3+8^3+10^3)= 4/3πr^3
216+512+1000=r^3
r^3=1728
r= 12

Answer:
Step-by-step explanation:
Sphere 1 (r)= 6 cm
sphere 2 (r)=8 cm
Sphere 3 (r)= 10 cm
Volume of newsphere= 4/3×22/7[ (6)cube+(8)cube+(10)cube]
=4/3×22/7[ 216+ 512 + 1000]
=88/21 [ 1728]
= 88/21×1728
=7241.14 cm(cube)
I HOPE U ALL UNDERSTOOD THE ANSWER AND BEST OF LUCK WITH YOUR EXAMS.
