Answer:

The height of cylinder is: h = 80.07 cm

The diameter of cylinder is: d = 3.5 cm

Step-by-step explanation:

Curved surface area of cylinder = 880 cm^2

Volume of cylinder = 770 cm^3

We need to find its diameter and height.

The formula used are:

Curved\: surface\: area=2\pi rh\\Volume=\pi r^2h

If we divide volume by curved surface, we can find radius

\frac{Volume}{Curved\: surface\: area}=\frac{\pi r^2h}{2\pi rh}  \\\frac{770}{880}=\frac{r}{2}\\0.875=  \frac{r}{2}\\=> r= 0.875\times 2\\r=1.75

So, we get radius r = 1.75

Now, we can find height using curve surface area formula:

Curved\: surface\: area=2\pi rh\\880=2(3.14)(1.75)h\\h=\frac{880}{10.99}\\h=80.07 \:cm

So, the height of cylinder is: h=80.07 cm

Now finding diameter using formula: d=2r

Putting value of r in above formula:

d=2r\\d=2(1.75)\\d=3.5\:cm\\

So, the diameter of cylinder is: d = 3.5 cm

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?
Nonamiya [84]
0.05n + 0.25q = 1.60
q = 3n

0.05n + 0.25(3n) = 160
0.05n + 0.75n = 1.60...multiply by 100 to get rid of the decimals
5n + 75n = 160...answer D
