Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2
Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2
Difference = larger are - smaller area
Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2
Answer: About 251 ft^2
Answer:you need use a scale and the numbers that are provided of the dimensions of the room
Step-by-step explanation:
Answer would be a (-1, ten-thirds) :)
35 divided by 2 1/2
change 2 1/2 to an improper fraction
2 1/2 = 5/2
35 divided by 5/2
copy dot flip
35 * 2/5
70/5
14
you can make 14 plots
