find the area of a cilider with radius s hight 4

Answer 1

To find the surface area of a cylinder, you can use the formula:

$$A=2\pi r(h+r)$$

where $r$ is the radius, and $h$ is the height of the cylinder.

Given:

• Radius $r=s$
• Height $h=4$

Substituting these values into the formula:

$$A=2\pi s(4+s)$$

So, the area of the cylinder is:

$$A=2\pi s(4+s)=8\pi s+2\pi s^2$$

This expression represents the surface area of the cylinder in terms of the radius $s$.

Answer 2

radius 2

Answer 3

Given the radius $r=2$ and height $h=4$, we can calculate the surface area of the cylinder using the formula:

$$A=2\pi r(h+r)$$

Substituting the values:

• $r=2$
• $h=4$

$$A=2\pi (2)(4+2)$$

Calculating $4+2$:

$$4+2=6$$

Now substitute back into the area formula:

$$A=2\pi (2)(6)=2\pi \times 2\times 6=24\pi$$

Therefore, the surface area of the cylinder is:

$$A=24\pi \text{square units.}$$

If you need a numerical approximation, you can use $\pi \approx 3.14$:

$$A\approx 24\times 3.14\approx 75.36\text{square units.}$$

Answer 4

find valume of cilinder with radius 3 hight 8

Answer 5

To find the volume of a cylinder, you can use the formula:

$$V=\pi r^{2}h$$

where:

• $r$ is the radius,
• $h$ is the height.

Given:

• Radius $r=3$
• Height $h=8$

Substituting these values into the formula:

$$V=\pi (3^2)(8)$$

Calculating $3^2$:

$$3^2=9$$

Now substitute back into the volume formula:

$$V=\pi (9)(8)=72\pi$$

Therefore, the volume of the cylinder is:

$$V=72\pi \text{cubic units.}$$

If you want a numerical approximation, using $\pi \approx 3.14$:

$$V\approx 72\times 3.14\approx 226.08\text{cubic units.}$$

So, the volume of the cylinder is approximately $226.08$ cubic units.
