Diameter=16

circumference=radius*2*3.14
50.24=r*2*3.14

1. divide 50.24 by 2
2. divide that answer by 3.14
3. this leaves you with the radius. multiply by 2 for the diameter

Hey there!

We know that ,

Circumference is a circle = 2 pi r

=> 2 pi r = 50.24

=> r = 50.24/2 x 3.14

=> r = 78.8 m

But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158

Option d is correct

Answer:

The answer to your question is - 8

Step-by-step explanation:

Data

The order of operations is

1st  Parenthesis

2nd Roots and exponents

3rd Multiplication and division

4rd Addition and subtraction

Following these rules

Parenthesis                                   (-1) 2* 5 + (3) 2/3

Multiplication and division          - 10 + (6/3)

                                                       - 10 + 2

in the figure below trianglePQM and triangleQRP are right triangles. the measure of lineQM is 6 and the measure of lineQP is 8.
Kipish [7]

Answer:

Option 4 is correct. The length of PR is 6.4 units.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR and triangle MQR.

Let the length of PR be x.

Pythagoras formula

hypotenuse^2=base^2+perpendicular^2

Use pythagoras formula for triangle PQM.

PM^2=QM^2+PQ^2

PM^2=(6)^2+(8)^2

PM^2=36+64

PM^2=100

PM=10

The value of PM is 10. The length of PR is x, so the length of MR is (10-x).

Use pythagoras formula for triangle PQR.

PQ^2=QR^2+PR^2

(8)^2=QR^2+x^2

64-x^2=QR^2                   .....(1)

Use pythagoras formula for triangle MQR.

MQ^2=QR^2+MR^2

(6)^2=QR^2+(10-x)^2

36=QR^2+x^2-20x+100

36-x^2+20x-100=QR^2        .... (2)

From equation (1) and (2) we get

36-x^2+20x-100=64-x^2

20x-64=64

20x=128

x=6.4

Therefore length of PR is 6.4 units and option 4 is correct.
