What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the circumference of the circle be represented as C

Now , the value of C is

The diameter of the circle d = 9 inches

Let the radius of the circle be r

And r = d/2

The value of r = 4.5 inches

And , the circumference of the circle C = 2πr

Substituting the values in the equation , we get

The circumference of the circle C = 2 x π x 4.5

On simplifying the equation , we get

The circumference of the circle C = 9 x π

The circumference of the circle C = 28.27 inches

Therefore , the value of C is 28.27 inches

Hence , the circumference of the circle is 28.27 inches

Daniel worked for 213213 hours and earned $18.20. How much would he make if he worked for 514514 hours? Enter your answer in the box.

Answers

convert the hours to improper fractions

2 and 1/3 hours=2+1/3=6/3+1/3=7/3
5 and 1/4=5+1/4=20/4+1/4=21/4

ratio and proprtion
time/pay=(7/3)/18.2
if work 21/4 hours how much is pay
(7/3)/18.2=(21/4)/pay
times both sides by 18.2pay aka cross multiply
(7/3)pay=(21/4)18.2
(7/3)pay=382.2/4
times both sides by (3/7) to clear fraction (7/3 times 3/7=21/21=1)
pay=1146.6/28
pay=40.95

will earn $40.95 in 5 and 1/4 hours

Is the gcf os a pair of numbers ever greater than both numbers ? explain with an example.

Answers

Answer:

No, G.C.F. of pair of numbers can never be greater than both numbers.

Step-by-step explanation:

G.C.F. (Greatest Common Factor) of pair of numbers is defined as the greatest factor of both the number that exactly divides both numbers.

For Example: G.C.F. of 14 and 21 =

36 = 2 × 2 × 3 × 3

48 = 2 × 2 × 2 × 2 × 3

Common Factors of 36 and 48 = 2 × 2 × 3 = 12

∴ G.C.F. = 12

As, we see that G.C.F. is factor of given number. So, it can never be greater than given numbers.

The gcf of numbers can never be greater than both numbers, because in order to be a gcf, it must be a factor that both numbers have, so if one number does not have that then it is not a gcf.
