Calculate the length of the circumference of a circle with diameter of 6.2cm

1 answer:

3 0

The formula for circumference is C=2*pi*radius. Therefore your setup would be C=2*pi*3.1. When you actually work this out you get 19.5 after rounding.

Find the length of JL 15 None of the other answers are correct 12 3

r-ruslan [8.4K]

Answer:

D: 12

Step-by-step explanation:

The entire segment KI is composed of the segments KJ and JI. So:

$KI=KJ+JI$

We know that KI is 15.

KJ is (2x-15) and JI is (2x-6). Substitute:

$15=(2x-15)+(2x-6)$

Solve for x. Combine like terms:

$15=4x-21$

Add 21 to both sides:

$4x=36$

Hence, the value of x is:

$x=9$

We know that JI is 2x-6.

We will substitute 9 for x to find JI. So:

$JI=2(9)-6=18-6=12$

Hence, our answer is D.

HELP 10 POINTS and brainliest! What is the value of X? △MAH∼△WCF .

german

The value of x is 23.

Simply find the scale factor or what was used to dilate △MAH to produce △WCF.

Use the equation copy over the original,

$k = \frac{c}{o} = \frac{15.5}{62}$

Reduce,

$\frac{15.5}{62} = \frac{1}{4} = 0.25$

So our scale factor is ¼ or 0.25

So if we use it and multiply the corresponding side of the missing side with the original we get,

$92 \times \frac{1}{4} = 23$

Therefore 23 is our missing side! !

how is finding the solution of a system of inequalities different from finding the solution of a system of equations? how is the

adoni [48]

Answer:

Step-by-step explanation:

The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.

Melody Pond and a tree cast a shadow at the same time of day. Melody is 5.6 feet tall and casts a 10-foot shadow. If the length

Elan Coil [88]

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets
