what is the area of a cirlce with the diameter of 42ft
Accepted Solution
A:
____________________________________________________Answer:Your answer would be 1,385.44 ft²____________________________________________________Step-by-step explanation:To find the area of a circle, we would use the equation [tex]\pi r^2[/tex]In this case we have the diameter, and that's 42.The radius of a circle is half of the diameter, therefore the radius would be 21.Now we know the radius,we can plug that in to our equation.Your equation should look like this:[tex]\pi (21)^2[/tex]Pi would be 3.14159Now, you can solve.[tex]3.14159(21)^2\\\\3.14159*441\\\\=1,385.44[/tex]When you'r edone solving, you should get 1,385.441,385.44 ft² would be your FINAL answer.____________________________________________________
