Answer:
Radius of sphere= 10 cm
Volume = 4/3πr^3 = 4/3 x 22/7 x 1000= 4190.47cm
Explanation:
Since it's increasing by 5%, the radius would be 10+5/100 = 10+1/20 = 201/20 = 10.05cm..
<em>THE</em><em> </em><em>NEW</em><em> </em><em>VOLUME</em><em> </em><em>NOW</em><em>.</em><em>.</em><em>.</em>
4/3πr^3 = 4/3 x 22/7 x (10.05)^3 = 4253.64 cm^3
<em>INCREASING</em><em> </em><em> </em><em>THE</em><em> </em><em>VOLUME</em>
(4253.64- 4190.47) cm ^3 = 63.17 cm^3
<em>INCREASING</em><em> </em><em>PERCENTAGE</em><em>.</em><em>.</em>
63.17/4190.47x100 = 1.5% (Answer)
I hope this helps you
