The formula for circumference of a circle is πd. Substitute the diameter and the rounded value of π in so you have 21*3.14.

Multiply to get 65.94 cm, which is the approximate circumference of the pizza.

The perimeter of a rectangle is 40 units. The length of the rectangle, L, is 7 units.
german

Answer:

L=7

W=13

Perimeter=40

Area=91

Step-by-step explanation:

Perimeter = 2L+2W

40=2(7)+2W

40=14+2W

-14  -14

26=2W

Divide both sides by 2

13=W

Area=L x W

7 x 13 = 91

Help with how to do these step by step?
zimovet [89]
Okay, so slope intercept form is y=mx+b. Like a normal problem with numbers, you add or subtract from each side. 
3x-2y= -16
you want to leave the y by itsself, so your going to add 3x to 16, but write it out how the formula is (y=mx+b). now, you should have -2y= -3x-16. (the three is now negative because you moved it to the other side of the equation.) 

now, remember that you want the y all by itself, so, all you have to do now is divide. 
-2y= -3x-16 ---------- now is y= -3/-2x minus 16/-2. (those are now fractions, but the y is alone.) now you simplify. 
-3/-2x is already simplified, but 16/-2 is not so it changes into -8,after dividing the fraction. 
now you have the answer. 
y= -3/2x-8x (it is the same as the formula now!)

hope this helps! it was hard to explain through typing but if you read it carefully, i explained every step.

Answer: Not sure but this may help!

Step-by-step explanation:

A = 7 —>

52 keys which means A is 7 keys to the right and there is about 7 A keys. 52 divided by 7 = around 7. I don’t know the question but I need points!
