Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
We have been given that
Radius of A = 24 cm
And Diameter of sphere B = 42 cm.
We know that radius is half of the diameter.
Hence, radius of sphere B = 42/2 =21 cm
Let the radius of sphere A is multiplied by 'k' to produce the radius of sphere B.
Thus, we have
[tex]24k=21[/tex]
Solve for k
[tex]k=\frac{21}{24}\\\\k=\frac{7}{8}[/tex]
Therefore, radius of sphere A is multiplied by [tex]\frac{7}{8}[/tex] to produce the radius of sphere B.
