Answer:

Step-by-step explanation:

Remark

The object is a cylinder.

Formula

V = pi * r^2 * h                               Substitute  givens in  the formula

Givens

V = 149 cm^3

h = 8.3

pi = 3.14

r = ?

Solution

149 = 3.14 * r^2 * 8.3                       Simplify

149 = 26.062 r^2                            Divide both sides by 26.062

149/26.062 = 26.062r^2/26.062

r^2 = 7.717                                       Take the square root of both sides

√r^2 = √7.717  

r= 2.391

Answer: r = 2.391
