How do i find the circumference of a circle? If I use a 3 as an estimate of pie and the circle is 10 mm across
Llana [10]
If you're using pie it would be

2*\pi*5 because the radius is half of the diameter.

But since you're using three it's

2*3*5

If it helps remember: Twinkle twinkle little star, circumference equals 2 pi r

How does a digit in the 10,000s place compared to a digit in the thousands place
enyata [817]
A digit in the ten thousands place will always be greater than the one in the thousands place. Even though the number in the ten thousands place is smaller it will still be greater because 10,000>1,000 right? For example,

Find the distance between the points ( 4, 7) and (-1,2
mihalych1998 [28]

Answer:

7.07 (3 significant figures)

Step-by-step explanation:

the distance between the two points on the x axis is 5 and the distance between the two point son the y axis is 5. thus by using pythagerous theorem you are able to get the hypotenuse which is the distance between the two points which in this case is 7.07 when rounded to 3 significant figures. not sure if im correct but i hope it helps

Given: <br> PQ<br> ⊥<br> QR<br> , PR=20,<br> SR=11, QS=5<br> Find: The value of PS.
dlinn [17]

Answer:

The value of the side PS is 26 approx.

Step-by-step explanation:

In this question we have two right triangles. Triangle PQR and Triangle PQS.

Where S is some point on the line segment QR.

Given:

PR = 20

SR = 11

QS = 5

We know that QR = QS + SR

QR = 11 + 5

QR = 16

Now triangle PQR has one unknown side PQ which in its base.

Finding PQ:

Using Pythagoras theorem for the right angled triangle PQR.

PR² = PQ² + QR²

PQ = √(PR² - QR²)

PQ = √(20²+16²)

PQ = √656

PQ = 4√41

Now for right angled triangle PQS, PS is unknown which is actually the hypotenuse of the right angled triangle.

Finding PS:

Using Pythagoras theorem, we have:

PS² = PQ² + QS²

PS² = 656 + 25

PS² = 681

PS = 26.09

PS = 26
