Question

Gift are packaged in cylinders

each cylinder is 12cm high with diameter of 8cm
calculate the volume of each cylinder
use 3 as a value for J

Answer 1

Explanation:

Radius r = 4 cm

Height h = 12 cm

Volume = πr²h = 192π cm³ ≈ 576 cm³

Answer 2

V = 192π cm³ ≈ 603 cm³

Explanation:

V = πR²h

V = π(8/2)²(12)

V = 192π cm³ ≈ 603 cm³

J = 3 Hooray, but why?
