Answer:

Step-by-step explanation:

Total surface area = 2πr(r+h)

If the total area of the bigger cylinder is 400cm² and radius is 4cm, then;

400=2(3.14)(r)(r+4)

400= 6.26r(r+4)

400=100.48 + 25.12h

299.52 = 25.12h

H = 299.52/25.12

H = 11.92cm

For the smaller cylinder

The height is calculated as;

H/h = R/r

11/92/

Arrange the following measurements in order from smallest to largest.
juin [17]

Answer:Arrange the following measurements in order from smallest to largest.

0.35 kilogram, 5 gram, 9.4 gram

Step-by-step explanation:Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.

According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.

We change 0.35kg to g

Since 1000g = 1kg

Then, 0.35kg = 0.35 × 1000

= 350g.

Rearranging the values, we have:

5 grams < 9.4 grams < 0.35 kilograms

Find the value of y.<br> Picture below
olga2289 [7]

We have trapezoid with congruent legs.

30x + 11y = 2x + 3

28x +11y = 3

Also we have

30x + 11y = 12

We got 2 equations:

30x + 11y = 12

28x +11y = 3 (*-1) -----> -28x -11y = -3

30x + 11y = 12

<u> -28x -11y = -3</u>

2x = 9

x=9/2

30x + 11y = 12 ------> 30*9/2 +11y =12 ------> 135+11y =12, ---> 11y = - 123,

y= - 123/11
