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
What is pi x 25?
pi X 25 = 25 pi ( Algebraic. However, if you approximate pi to 3.14159 Then 3.14159 x 25 = 78.53975 If you approximate pi tp 3.13 Then 3.14 x 25 = 78.5
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)
A circular mirror is surrounded by a square metal frame the radius of the mirror is 5x the side length of the metal frame is 15x what is the area of the metal frame write your answer in factored form?
To find the area of the metal frame, we first calculate the area of the circle and the area of the square. The radius of the mirror is (5x), so the area of the circle is (\pi (5x)^2 = 25\pi x^2). The side length of the square is (15x), so the area of the square is ((15x)^2 = 225x^2). The area of the metal frame is the area of the square minus the area of the circle: [ 225x^2 - 25\pi x^2 = (225 - 25\pi)x^2. ] Thus, the area of the metal frame in factored form is ((225 - 25\pi)x^2).

What is the area of a diameter of 25 feet?
25 x pi sqft
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)
What is pi x 25?
pi X 25 = 25 pi ( Algebraic. However, if you approximate pi to 3.14159 Then 3.14159 x 25 = 78.53975 If you approximate pi tp 3.13 Then 3.14 x 25 = 78.5

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.
