If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft.
so the original area is
A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
so the ratio of the ratio the area in the drawing to the actual area is:
r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft
Step-by-step explanation:
6 I think that is the answer I hop you get it right
Hey there!

We can first factor out the 4 (bring it outside the parenthesis)

Now have a closer look between the parenthesis, because this expression can be factored as well. We're looking for two different numbers with a product of -6 and a sum of 5. Hence, we find the numbers 6 and -1
