$\large\boxed{\green{\boxed{\red{\boxed{\blue{\boxed{\boxed{\boxed{\red{メSђสŇtสŇบ࿐}}}}}}}}}}$

Answer 2

Answer:

7cm

Step-by-step explanation:

Given:

Volume = 3850 cm3 Length i.e. height = 1 m = 100 cm

Volume = r2h

22/7 x r2 x 100 = 3850

r2 = 3850/100 x 7/22

r2 = 12.25

r = v12.25

r = 3.5

So, the diameter of the rod is 2 x 3.5 i.e. 7cm
