Find the surface area of a cylinder. Solve this formula for h. Then find the height of the cylinder if the surface are is 251.2

mezya [45]

Answer:

The formula for 'h' is $\frac{S.A.}{2\pi r}-r$ .

The height of the cylinder is 3 in.

Step-by-step explanation:

Given,

Surface Area of Cylinder = 251.2 sq. in.

Radius = 5 in

We have to find out the height of the cylinder.

Solution,

We know that the Surface area of cylinder is given as;

$Surface\ Area = 2\pi r(h+r)$

Here 'r' is the radius and 'h' is the height.

We have to solve this for 'h'.

$\frac{S.A.}{2\pi r}=h+r\\\\h=\frac{S.A.}{2\pi r}-r$

Hence The formula for 'h' is $\frac{S.A.}{2\pi r}-r$ .

Now we solve for 'h'.

Since $h=\frac{S.A.}{2\pi r}-r$

On putting the given values, we get;

$h=\frac{251.2}{2\times3.14\times5}-5=8-5=3\ in$

Hence The height of the cylinder is 3 in.

Johns dog slept for 3 hours if the dog snored every 1/3 of an hour how many times did he snore

Licemer1 [7]

The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
