The ratio of the length of two similar re rectangles is 3 ratio 4. what is the scale ratio of their areas in full solving​

9:16

Step-by-step explanation:

The ratio of sides of the lengths of rectangles is 3:4.

That is :-

→ Ratio of Area = ( 3 : 4)²

→ Ratio of Area = (3/4)²

→ Ratio of Area = 9/16

→ Ratio of Area = 9:16

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
