Question

anybody can tell this answer with explanation ​

Answer 1

Answer:

Ratio=8:1

Step-by-step explanation:

Let the radius be 1

therefore volume= 4/3 π r ^3

v1=4/3 * 22/7 * 1*1*1

v1=88/21

Volume doubled=

r2=1*2=2

v2=4/3 * 22/7 * 2*2*2

v2=(88 x 8)/21

Let not be solved

RATIO= v2:v1

Ratio=(88 x 8/21) x 21/88                 Taking reciprocals

Ratio=8:1
