To solve number 10, you should do just as it says and type it into a calculator. To save you the trouble, I have already done this. It equals approximately 4.26.

As for number 11, you have not included the whole question, so there is not currently enough information to solve it.

A round cake has a diameter of 30\text{ cm}30 cm30, start text, space, c, m, end text. Angela places the cake on a circular cake

Answer:

The circumference of the cake board is <u>35π cm</u>.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

A round cake has a diameter of 30 cm. Angela places the cake on a circular cake board with a diameter 5 cm longer than that of the cake. What is the circumference of the cake board? Give your answer in terms of π.

Now, to find the circumference of the cake board.

As, given diameter of cake = 30 cm.

And diameter of cake board is 5 cm longer than that of the cake.

Thus, the diameter of cake board is:

$30\ cm+5\ cm=35\ cm.$

So, to find the circumference we need radius, by putting formula:

$Radius(r)=\frac{Diameter}{2}$

$Radius(r)=\frac{35}{2}$

$Radius(r)=17.5\ cm.$

Now, to get the circumference of the cake board we put formula:

$Circumference=2\pi r.$

$Circumference=2\times \pi \times 17.5$

$Circumference=35\pi \ cm.$

Therefore, the circumference of the cake board is 35π cm.

Please help I need an answer fast

sp2606 [1]

All you need to do is use the formula to solve. What I do is I plug in the information that I know, and then I just solve. In this case it would be:

V= (4)
- pie(3.14)*4.8(cubed)

How to solve x/-3-2=5.5

amid [387]

Okay first set up the equation

x
--- -2 = 5.5
-3

add over the 2

x
--- = 7.5
-3

now you need to multiply the denominator by the answer

(-3)(7.5) = x
-22.5 = x
