What is the diameter of a circle if the circumference 314 feet?
Diameter = 314/pi feet
What is the Surface Area of a cylinder with diameter of 12 cm and a height of 20 cm?
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
What is the area of a circle with a radius of 10 in using 3.14 for pi?
Using 3.14 as Pi the area of circle is: 314.0
How do you get the circumference out of the area?
you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
What is the square footage of a 10 foot radius circle?
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
