Find the circumference and area r = 5 m

Mathematics
1 answer:
stira [4]3 years ago
4 0

Step-by-step explanation:

Let's get our relevant base equations listed out:

d = 2r

area = pi*r²

c = πd

Thus, d=2*5m  = 10m, c=π*10m=10π m, and area = 25m²*π

Sally needs 2/3 of a pound of potatoes. This is 1/3 of a pound more than 4/3 of the potatoes Sally has in her pantry
amid [387]

Lets assume, Sally has X pound of potatoes in her pantry.

So, 4/3 of the potatoes Sally has in her pantry = \frac{4}{3}X

Now, Sally needs 2/3 pound of potatoes and this 2/3 pound of potatoes is 1/3 pound more than that \frac{4}{3}X

So the representing equation will be:

\frac{2}{3} =  \frac{1}{3}+ \frac{4}{3}X

\frac{2}{3} - \frac{1}{3} = \frac{4}{3} X (subtracting \frac{1}{3} from both sides)

\frac{1}{3}= \frac{4}{3}X

1= 4X (multiplying both sides by 3)

X =\frac{1}{4}

So, Sally has \frac{1}{4} pound of potatoes in her pantry.

Stella [2.4K]

Answer:

8 different combinations are possible.

Step-by-step explanation:

Here, we have 2 different combinations for each time.

And the player comes out to bat 3 times.

So, total number of combinations are:

2^{3} i.e. a total of 8 number of times.

Let a hit is termed as 'H' and an out is termed as 'O'.

Total combinations are:

{HHH, HHO, HOH, HOO, OHH, OHO, OOH, OOO}

Kindly have a look at the tree diagram attached in the answer area.

In starting, there are 2 combinations possible, i.e. 'O' and 'H'.

After 'O' , 2 possible i.e. 'O' and 'H'.

After 'H' , 2 possible i.e. 'O' and 'H'.

and so on....

Let R be the triangular region in the first quadrant with vertices at.Points (0,0), (h,0), and (h,r), where r and h are positive
Romashka [77]

Answer:

The answer is "\pi  \int^{h}_{0}(\frac{r}{h} x)^2 \ dx"

Step-by-step explanation:

dv=(Area) \ thickness

    =\pi r^2 \ dx\\\\=\pi (\frac{r}{h} x)^2 \ dx  

V= \int^{h}_{0} \pi (\frac{r}{h} x)^2 \ dx\\\\

   =\pi  \int^{h}_{0}(\frac{r}{h} x)^2 \ dx
