Answer:
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
