What is the area of circle with the radius 25inches?
Area of Circle = pi x r^2 = pi x 25 x 25 = pi x 625 If you need a decimal answer multiply 625 x 3.14159
What is the area of a diameter of 25 feet?
25 x pi sqft
How do you find the circumference of a circle if you have the area and nothing else?
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
What is the circumference if the radius is .25?
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375

What is the area of a diameter of 25 feet?
25 x pi sqft
Leaving the answer in terms of pi what is the area of a circle with a circumference of 50 pi cm?
Circumference = pi x diameter = 50 pi The diameter is 50. Radius is half of the diameter, which is 25. Area = pi x r2 = pi x 252 = 625 pi cm
What is the area of a circle that has a diameter of 10 ft?
25 pi sqft A= pi X r2 A= 3.14 X 52 A= 3.14 X 25 A= 78.5 ft.2
If the perimeter is 20 what is the highest area you can get?
A circle, radius 10/pi has an area of pi x 10/pi x 10/pi ie 100pi/pi2 ie 100/pi ie 31.8; A square 5 to the side has an area of 25.
Fionna has 20 feet to put around a garden.what is the greatest area for the garden that she can make?
A square of side 5 would have an area of 25 sqft, but a circle of circumference 20 ft would have a bigger area: circumference = 2 x pi x r = 20 so r = 10/pi. Area = pi x r x r = pi x 10/pi x 10/pi which = 100 pi /pi x pi ie 100/pi which is about 31.8 sq ft.
If you have a 5 km radius what is the area in unit of square km?
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
How do you find the circumference of a circle if you have the area and nothing else?
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)
What is the largest area that you can have if the perimeter is 24 feet?
You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.

How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
What is the circumference if the radius is .25?
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
What shape will have the largest area with a perimeter of 100cm?
Circle, followed by square. circumference = 2 pi r so pi r = 50 so r = 50/pi; Area of circle = pi r2, = 2500/pi = 795.5 sqcm Square = 25 x 25 = 625 sqcm.
