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.
How do you find area of a cylinder?
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
Find the radius of a circle if its area is 254.5 square inches?
The formula for the area of a circle is pie r squared therefore if pie r squared = 254.5 r squared = 254.4 divided by pie = 81.009... r = square root of 81.009... = 9.000... = 9 ( correct to the nearest whole number) therefore radius of this circle is 9
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
Is the area of a circle cubed or squared?
a circle is a round object. since an area is a two dimensional concept not a three dimensional concept like a volume,the area of a circle is squared. GIVEN BY THE FORMULA A=pie x r(radius)squared. pie=3.14159265
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 does the R mean in pie R squared?
radius
How do you a just the circumference of a circle?
pie r squared
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.
How do you find area of a cylinder?
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
What is the value of r³?
As in pie r squared? r = radius.
Find the radius of a circle if its area is 254.5 square inches?
The formula for the area of a circle is pie r squared therefore if pie r squared = 254.5 r squared = 254.4 divided by pie = 81.009... r = square root of 81.009... = 9.000... = 9 ( correct to the nearest whole number) therefore radius of this circle is 9
What is the rule for pie r squared?
Area of a circle = pi*radius2
Why is it pie r squared is the exactly formula for circumference?
It isn't. That is the formula for the AREA of a circle!
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
How do you calculate the area of circle?
Area: (pi)(r)2
What is the area of a circle that has a radius of 4?
PIE r squared 3.142 X 42 = 50.24
