Question

PLEASE HELP!!!!!!!!!!!

Answer 1

V = π*4²*12=603,2cm³

Explanation:

Answer 2

603.2 cm³ (1 d.p.)

Explanation:

The formula for the volume of a cylinder is:

`\large\boxed{V=\pi r^2h}`

where:

• V is the volume.
• r is the radius of the circular base.
• h is the height.

To calculate the volume of a cylinder with radius 4 cm and height 12 cm, substitute r = 4 and h = 12 into the volume formula:

`\begin{aligned}V&=\pi \cdot 4^2 \cdot 12\\&=\pi \cdot 16 \cdot 12\\&=\pi \cdot 192\\&=603.185789...\\&=603.2\; \sf cm^3\;(1\;d.p.)\end{aligned}`

Therefore, the volume of the given cylinder is:

`\Large\boxed{\boxed{603.2\; \sf cm^3\; (1\;d.p.)}}`
