The area of the circular shaped patio is: 172.7 ft²
<h3>What is the Area of a Circle?</h3>
Area of a circle = πr² [r is given as the radius of the circle].
The area of the patio = area of the larger circle - area of the smaller circle.
Radius of the larger circle = 8 cm
Radius of the smaller circle = 3 cm
π = 3.14
Area of smaller circle = πr² = (3.14)(3²)
Area of smaller circle = 28.26 cm²
Area of bigger circle = πr² = (3.14)(8²)
Area of bigger circle = 200.96 cm²
The area of the patio = 200.96 - 28.26
The area of the patio = 172.7 ft²

I assume you mean the total number of jazz and classical songs combined is 28 songs?
3 times as many jazz as classical:
Means there is a ratio of 3 jazz to 1 classical, which means there are essentially 4 parts (3+1=4). So if we divide 28/4=7. This gives one part = number of classical songs, jazz is 3 parts so 7*3=21 jazz songs.
7 times as many rock as classical:
From above we know there are 7 classical songs. 7*7=49 rock songs.
Jazz=21 songs
Rock=49 songs
