Answer:

The volume of a cylinder:

$V \approx 150.796$ $ft^3$

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

$V = \pi r^2h$

-Use the given height and radius for the formula:

$V = \pi 4^2 3$

-Then, solve the formula:

$V = \pi \times 4^2 \times 3$

$V = \pi \times 16 \times 3$

$V = \pi \times 48$

$V = 48\pi \approx 150.796$

So, the volume of a cylinder is approximately $150.796$ $ft^3$ .

Could you guys help me find the area of these please? i don't understand how to do this

Answer:

for 9, the answer is 246.49

Step-by-step explanation:

This is area of a circle correct?

The formula is PI x radius squared.

3.14 x the radius, which is 5, squared

I am re-editing this

so sorry the answer is actually 78.54

The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
