Bobby made cookies. the circumference of cookies are 6 cm. what is the diameter of the cookies?

1 answer:

4 0

To find the circumference you would multiply the diameter by pi(3.14) so you do the opposite. Divide 6 by 3.14 (pi) and you should get your answer: 19.1 or something similar.

It is easy! I got you! So if Gavin earned $25 more then Seiji and the total of money they got over the summer is $425, all you have to do is subtract, so 425- 25= 400. Seiji earned s and Gavin earned g.

Answer:

325 square inches

Step-by-step explanation:

Consider the attachment below for further reference. Ideally we would split this figure into parts, and solve as demonstrated by the attachment. I have labeled each rectangle as rectangle 1, rectangle 2, rectangle 3 etc. ;

$Rectangle 1 Area = 17 in * 5 in = 85 square in\\Rectangle 2 Area = ( 17 in - 5 in ) * 14 in = 168 square in,\\Rectangle 3 Area = ( 12 in - 3 in ) * 8 in = 72 square in\\\\Total Area = 85 + 168 + 72 = 325 square inches$

Hope that helps!

The equation of a circle is given below. 9 x^2+ (y - 7.5)^2 =9/49 What is its center?

My name is Ann [436]

Answer:

(0, 7.5)

Step-by-step explanation:

Compare the equation to the standard-form equation of a circle:

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . center at (h, k); radius r

You will notice that ...

h = 0

k = 7.5

The center is (h, k) = (0, 7.5).

The sum of 9 and three times a number is 21. What is the number? equation: n =

Yakvenalex [24]

To solve equations like this we need to do inverse operations.

First we need to build an equation: 9+3x=21

We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12

After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4

Now let's double check:

N=4, since 3*4=12 and 12+9=21

Hope it is helpful :)
