Given:

Radius of a cylinder = 5 units.

Surface area of the cylinder = 160\pi

To find:

The height of the right cylinder.

Solution:

Surface area of a cylinder is:

A=2\pi rh+2\pi r^2

Where, r is radius and h is the height of the cylinder.

Putting r=5, A=160\pi in the above formula, we get

160\pi =2\pi (5)(h)+2\pi (5)^2

160\pi =10\pi h+2\pi (25)

160\pi =10\pi h+50\pi

Subtract 50\pi from both sides.

160\pi -50\pi=10\pi h

110\pi=10\pi h

Divide both sides by 10\pi.

\dfrac{110\pi}{10\pi}=h

11=h

Therefore, the height of the cylinder is 11 units.

Interest earned: $294<br> Principal: $600<br> Interest rate: 7%<br> Time:
ICE Princess25 [194]

Answer: 7 years

Step-by-step explanation:

Given the formula for simple interest as

Principal × Rate × Time

To find Time is therefore 100 × Interest/ Principal x Rate

From the above question,

Principal is given as 600;

Interest is 294 and

Rate is 7%

Slot the values into the formula:

100 × 294/ 600 x 7

= 29400/4200

=7

Therefore, Time (T) is 7 years

I hope this is clear, please mark as brainliest
