If 9 ft is the diameter then 9 pi ~ 28.2743339 If 9 ft is the radius then 18 pi ~ 56.5486678
11 ft * 9ft = 11*9 sq ft = 99 sq ft
9 ft square means a square of 9ft sides. The area will be 81 square feet
9 * 12 = 108 sq ft.
the diameter of a circle with the radius of 9m is 18m
If 9 ft is the diameter then 9 pi ~ 28.2743339 If 9 ft is the radius then 18 pi ~ 56.5486678
the circumfrence of a circle is pi times it's radius squared.
A circle with a radius of 9 feet has an area of 254.47 square feet.
11 ft * 9ft = 11*9 sq ft = 99 sq ft
Circumference = 2(pi)r if diameter = 18ft then the radius is 9ft, so: Circumference = 2(pi)9 = 56.54ft =] -ray
area of circle = pi x radius squared where pi = 3.1416 radius = diameter/2 = 18/2 = 9 ft area = 3.1416 x 9 x 9 sq ft = 254 sq ft
9 ft by 9 ft = 81 square feet 81 square feet = 7.52515 square meters.
250 sq.ft. is the area of the circle. Apply the Area eq'n A = pi r^2 Algebraically rearrange r^2 = A/ pi r = sqrt(A/pi) Substituting r = sqrt( 250/3.141592....) r = sqrt(79.57747165...) r = 8.920620581.... ft. r = 8 ft 11.047... inches. ~ 9ft
9 ft = 3 yrds.
9ft = 3yds
9 feet + 1/3 of 9 feet = 9 ft + 9/3 ft = 9ft + 3 ft = 12 ft.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
