What is the circumference and area of a 8 in circle?
if the radius is 8 in then circumference = 2 pie r= 2 * 3.14 * 8= 50.24 in area = pie * r * r = 3.14 *8 * 8= 200.96
How do you calculate the area of circle?
Area: (pi)(r)2
What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
What is the formula of the surface area of a circle?
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
What is the circumference of a 12 inch round circle for the area?
well the formula is 2 pie r
What is the formula for calculating the area of a circle?
Area of circle = pie x (r squared) = πr^2 r = radius π = pie = 22/7 or 3.142
What is the formula used for finding area of a circle?
area= pie*(r^2) = πr2
What is the circumference and area of a 8 in circle?

How do you calculate the area of circle?
Area: (pi)(r)2
What is 2 pie r sqaured?
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
What is the formula of the surface area of a circle?
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
What is the circumference of a 12 inch round circle for the area?
well the formula is 2 pie r
What is the formula for the area A of a circle?
Area = pi*radius2A = Pi*R-squaredPi * R^2
How do find the diameter of the circle in terms of pi?
perimeter of a circle = pie *r^2 Hence r^2 = perimeter/ pie hence r = (perimeter/Pie)^1/2 Hence diameter = 2r= 2* ( perimeter?pie) ^1/2
What is the Diameter of circle with a area?
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
What is the area of a circle with an radius of 17 feet?
Area of a circle is found by: A = (Pie)(r2) Plug in 17 for 'r'. A = (Pie)(172) A = 907.920277 ft.
