Please help me I reallly can’t do this

Answer 1

11 mm

Explanation:

Put the given numbers in the given formula and solve for the radius.

V = 1/3πr²h

968π = 1/3π·r²·24

121 = r² . . . . . . . . . . . divide by 8π

r = √121 = 11 . . . . . . take the square root

The radius of the piece is 11 mm.
