An amusement park has two merry-go-rounds. The first merry-go-round has a platform with a diameter of 13 meters and the second merry-go-round has a platform with a radius of 9.5 meters. How much larger is the area of the larger merry-go-round’s platform compared to the area of the smaller merry-go-round’s platform? Round to the nearest whole number. Show your work. (Use Pi = 3.14)

Explanation:

The area of a round shape is equal to the area of a circle.

The formula for the area of a circle is:

Then, use that formula for each merry-go-round.

1. First merry-go-round

2. Second merry-go-round

3. Difference of the areas

Hence, the larger merry-go-round's platform is 151m² larger than the smaller merry-go-round's platform.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
