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
25 x pi sqft
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
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)
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).

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.
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.
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)

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. 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. 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. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
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.
