FORMULA:

Volume of cylinder = πr²h
Volume of sphere = 4/3πr³

ANSWER:

Volume of capsule = 4/3πr³ + πr²h

πr²(4/3r + h)

3.14 × 2²(8/3 + 5.6)
3.14 × 4(2.6 + 5.6)
12.56(8.2)
102.99 or 103 rounded.

Length of a rectangle is four times its width. If the perimeter is 100 m, what is the area in square cm?

melisa1 [442]

Set the width to be x. Thus, the length is 4x.

The perimeter is 2(x+4x)=100, so x=10.

Plugging in x=10, you get that 4x=40.

So, the area of the rectangle is 400 $m^2$ .

Because there are 100 centimeters in a meter and you are asking for area, you must multiply by $100^2$ to get 4000000 $cm^2$ .
