If the diameter of a circle with a circumference of 19.5 inches is reduced by three, what would be the circumference of the new circle?

It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .

And the formula of circumference is

Substituting the value of C, we will get

When the diameter increased by 3, then the circumference is

And the circumference , when diameter is increased by 3 is 29 inches .

Since the circumference of a circle = 19.5 inches

r = 3.1 inches

So, diameter = 2r = inches.

Since. the diameter of new circle is reduced by three.

Therefore, D = 6.2-3 = 3.2 inches.

R = 3.2 inches

Now, circumference of new circle

=

=

=10 inches

So, the circumference of the new circle is 10 inches.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
